target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific). Replace it with a finger-friendly,
standards conformant hwaddr.
Outstanding patchsets can be fixed up with the command
git rebase -i --exec 'find -name "*.[ch]"
| xargs s/target_phys_addr_t/hwaddr/g' origin

Introduce type constant. Introduce cast macro to drop dummy busdev field
used with FROM_SYSBUS() that would've broken SYS_BUS_DEVICE().
Avoid accessing parent fields directly.
Drop no-op reset function.

This is now done sloppily, via get_system_memory(). Eventually callers
will be converted to stop using that.

During testing, I was generating a vmlinux binary that easily occupied
more than 20MB of RAM. Since the current -kernel code loads the initrd
at a fixed address behind the kernel, we were overwriting kernel data
when the kernel got too big.
To finally get rid of the issue, let's calculate the initrd and cmdline
addresses relative to the kernel size, so we can have kernels and initrds
that are as big as they want to - as long as they fit in RAM.

The "Mac99" type so far defines a "U2" based configuration. Unfortunately,
there have never been any U2 based PPC64 machines. That's what the U3 was
developed for.
So let's split the Mac99 machine in a PPC64 and a PPC32 machine. The PPC32
machine stays "Mac99", while the PPC64 one becomes "Mac99_U3". All peripherals
stay the same.

In the very least, a change like this requires discussion on the list.
The naming convention is goofy and it causes a massive merge problem. Something
like this _must_ be presented on the list first so people can provide input
and cope with it.
This reverts commit 99a0949b72.

My self-built PPC kernel doesn't fit in the region reserved for
the kernel, so I can't use -kernel with it.
Let's just extend the region.

* make PowerPC NVRAM accessors generic to be able to use a MacIO NVRAM
instead of the M48T59 one
* split PowerMac targets code:
- move all PowerMac related definitions and prototypes into hw/ppc_mac.h
- add hw/mac_dbdma.c, hw/mac_nvram.c and macio.c
which implements shared PowerMac devices
- define the g3bw machine in a new hw/ppc_oldworld.c file
* Fix the g3bw target:
- fix the Grackle host PCI device
- connect the Heathrow PIC to the PowerPC 6xx bus pins
