Don't conditionalise GEM instantiation on networking attachments. The
device should always be present even if not attached to a network.
This allows for probing of the device by expectant guests (such as
OS's). This is needed because sysbus (or AXI in Xilinx's real hw case)
is not self identifying so the guest has no dynamic way of detecting
device absence.
Also allows for testing of the GEM in loopback mode with -net none.

cgcc reported a duplicate initialisation. Mainstone includes a matrix
keyboard where two different positions map to 'space'.
QEMU uses the reversed mapping and does not map 'space' to two different
matrix positions.
Some other keys are either missing or might be mapped wrongly (cf. Linux
kernel code). Don't fix these until someone can test them with real
hardware, but add TODO comments.

device_add plugs devices into suitable bus. For "real" buses, that
actually connects the device. For sysbus, the connections need to be
made separately, and device_add can't do that. The device would be
left unconnected, and could not possibly work.
Quite a few, but not all sysbus devices already set
cannot_instantiate_with_device_add_yet in their class init function.
Set it in their abstract base's class init function
sysbus_device_class_init(), and remove the now redundant assignments
from device class init functions.

In an ideal world, machines can be built by wiring devices together
with configuration, not code. Unfortunately, that's not the world we
live in right now. We still have quite a few devices that need to be
wired up by code. If you try to device_add such a device, it'll fail
in sometimes mysterious ways. If you're lucky, you get an
unmysterious immediate crash.
To protect users from such badness, DeviceClass member no_user used to
make device models unavailable with -device / device_add, but that
regressed in commit 18b6dad. The device model is still omitted from
help, but is available anyway.
Attempts to fix the regression have been rejected with the argument
that the purpose of no_user isn't clear, and it's prone to misuse.
This commit clarifies no_user's purpose. Anthony suggested to rename
it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which
I shorten somewhat to keep checkpatch happy. While there, make it
bool.
Every use of cannot_instantiate_with_device_add_yet gets a FIXME
comment asking for rationale. The next few commits will clean them
all up, either by providing a rationale, or by getting rid of the use.
With that done, the regression fix is hopefully acceptable.

For AArch64 we will obviously require a different set of
primary and secondary boot loader code fragments. However currently
we hardcode the offsets into the loader code where we must write
the entrypoint and other data into arm_load_kernel(). This makes it
hard to substitute a different loader fragment, so switch to a more
flexible scheme where instead of a raw array of instructions we use
an array of (instruction, fixup-type) pairs that indicate which
words need special action or data written into them.

Fix NOR flash manufacturer and device ID reading. This now
properly takes into account device widths and device max widths
as required. The reading of these IDs uses the same max_width
dependent addressing as CFI queries.
The old code remains for chips that don't specify a device width,
as the new code relies on a device width being set in order to
properly operate. The existing code seems very broken.
Only ident0 and ident1 are used in the new code, as other fields
relate to the lock state of blocks in flash.
The VExpress flash configuration has been updated to match
the new code, as the existing definition was 'wrong' in order
to return the expected results with the broken device ID code.

We set default boot order "cad" in every single machine definition
except "pseries" and "moxiesim", even though very few boards actually
care for boot order, and "cad" makes sense for even fewer.
Machines that care:
* pc and its variants
Accept up to three letters 'a', 'b' (undocumented alias for 'a'),
'c', 'd' and 'n'. Reject all others (fatal with -boot).
* nseries (n800, n810)
Check whether order starts with 'n'. Silently ignored otherwise.
* prep, g3beige, mac99
Extract the first character the machine understands (subset of
'a'..'f'). Silently ignored otherwise.
* spapr
Accept an arbitrary string (vl.c restricts it to contain only
'a'..'p', no duplicates).
* sun4[mdc]
Use the first character. Silently ignored otherwise.
Strip characters these machines ignore from their default boot order.
For all other machines, remove the unused default boot order
alltogether.
Note that my rename of QEMUMachine member boot_order to
default_boot_order and QEMUMachineInitArgs member boot_device to
boot_order has a welcome side effect: it makes every use of boot
orders visible in this patch, for easy review.

Drop the now-deprecated arm_pic_init_cpu() in favour of directly
