Instead of ignoring any errors that occur when adding properties
to a new device in device_initfn(), check for them and abort if any
occur. The most likely cause is accidentally adding a duplicate
property, which is a programming error by the device author.

On real hardware the ppc hash page table is stored in memory; accordingly
our mmu emulation code can read a hash page table in guest memory. But,
when paravirtualized under PAPR, the real hash page table is in host
memory, accessible to the guest only via hypercalls. We model this by
also allowing the MMU emulation code to access a specially allocated hash
page table outside the guest's memory image. At present these two options
are implemented with some ugly conditionals at each access point in the mmu
emulation code. In the implementation of the PAPR hypercalls, we assume
the external hash table.
This patch cleans things up by adding helpers to load and store from the
hash table for both 32-bit and 64-bit hash mmus. The 64-bit versions
handle both the in-guest-memory and outside guest memory cases. The 32-bit
versions only handle the in-guest-memory case since no 32-bit systems can
have an external hash table at present.

Currently cpu.h contains a number of definitions relating to the 64-bit
hash MMU. Some are used in the MMU emulation code, but some are only used
in the spapr MMU management hcall implementations.
This patch moves these definitions (except for a few that are needed
more widely) into mmu-hash64.h header, shared between the MMU emulation
code and the spapr hcall code. The MMU emulation code is also updated to
actually use a number of those definitions in place of hard coded
constants.
Similarly, we add new analogous definitions to mmu-hash32.h and use those
in place of many hard-coded constants in mmu-hash32.c

Currently, the pseries machine initializes the cpus, then the XICS
interrupt controller. However, to support the upcoming in-kernel XICS
implementation we will need to initialize the irq controller before the
vcpus. This patch makes the necesssary rearrangement. This means the
xics init code can no longer auto-detect the number of cpus ("interrupt
servers" in XICS terminology) and so we must pass that in explicitly from
the platform code.

Currently the "spapr-pci-host-bridge" device has a "busname" property which
can be used to override the default assignment of qbus names for the bus
subordinate to the PHB. We use that for the default primary PCI bus, to
make libvirt happy, which expects there to be a bus named simply "pci".
The default qdev core logic would name the bus "pci.0", and the pseries
code would otherwise name it "pci@800000020000000" which is the name it
is given in the device tree based on its BUID.
The "busname" property is rather clunky though, so this patch simplifies
things by just using a special case hack for the default PHB, setting
busname to "pci" when index=0.

Exception: eepro100 is not switched, it uses a single rom for all

fly with the correct PCI IDs. I doubt that will work as-is with

Implement the SYS_CFG_OSC function. Since the idea of
programmable clock rates doesn't make much sense for QEMU,
we simply allow the clock rate to be read back as written.
The number and value of the daughterboard oscillators varies
between daughterboards, so we provide an array property to
allow their reset values to be configured.

Implement the SYS_CFG_VOLT registers which return the voltage
of various supplies on motherboard and daughterboard. Since
QEMU implements a perfectly stable power supply these registers
always return a constant value. The number and value of the
daughterboard voltages is dependent on the specific daughterboard,
so we use a property array to allow the board to configure them
appropriately.

Add support for declaring array properties for qdev devices.
These work by defining an initial static property 'len-arrayname'
which the user of the device should set to the desired size
of the array. When this property is set, memory is allocated
for the array elements, and dynamic properties "arrayname[0]",
"arrayname[1]"... are created so the user of the device can
then set the values of the individual array elements.

SYS_CFG_DVIMODE allows the guest to select whether the
output DVI signal is VGA, SVGA, XGA, SGA or UXGA. Since
this makes no difference to QEMU, implement writes as a

SYS_CFG_MUXFPGA allows the guest to select whether the
video output should come from the motherboard's LCD
controller or the daughterboard's one. Since QEMU doesn't
currently support selecting the video output like this,
implement as a no-op, so Linux doesn't complain about
the register not being implemented.

The SYS_CFGCTRL register consists of separate fields
for DCC, function, site, position and device, as well
as a read/write bit. Refactor the code handling SYS_CFGCTRL
writes to make it easier to add support for functions
like SYS_CFG_OSC which support multiple device fields.
We also pull the handling out into its own function for
clarity, as there are potentially a lot of implementable
subfunctions.

Pass the daughterboard-specific proc_id property to the code that
creates the sysctl device via the VEDBoardInfo struct, rather than
by having the daughterboard init function write to a uint32_t*
argument. This is a cleaner way to pass the info around, and
is in line with the way we are going to handle voltage and
oscillator initialization.

The bug is that the EventNotifiers do have a NULL io_flush callback.
Because _none_ of the callbacks on the dataplane AioContext have such a
callback, aio_poll will simply do nothing. Fixed by adding the callbacks:
the ioeventfd will always be polled (this can change in the future to
pause/resume the processing during live snapshots or similar operations);
the ioqueue will be polled if there are outstanding requests.
I must admit I have screwed up my testing somehow, because commit
2c20e71 does not work even if cherry-picked on top of 1.4.0, and this
patch fixes it there as well.

Currently, for the pseries machine the device tree supplied by qemu to SLOF
and from there to the guest does not include a 'compatible property' at the
root level. Usually that works fine, since in this case the compatible
property doesn't really give any information not already found in the
'device_type' or 'model' properties.
However, the lack of 'compatible' confuses the bootloader install in the
SLES11 SP2 and SLES11 SP3 installers. This patch therefore adds a token
'compatible' property to work around that.
