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.

Add 'virt' platform support corresponding to arch/arm/mach-virt
in the Linux kernel tree. This has no platform-specific code but
can use any device whose kernel driver is is able to work purely
from a device tree node. We use this to instantiate a minimal
set of devices: a GIC and some virtio-mmio transports.

[PMM:
Significantly overhauled:
* renamed user-facing machine to just "virt"
* removed the A9 support (it can't work since the A9 has no
generic timers)
* added virtio-mmio transports instead of random set of 'soc' devices
(though we retain a pl011 UART)
* instead of updating io_base as we step through adding devices,
define a memory map with an array (similar to vexpress)
* similarly, define irqmap with an array
* folded in some minor fixes from John's aarch64-support patch
* rather than explicitly doing endian-swapping on FDT cells,
use fdt APIs that let us just pass in host-endian values
and let the fdt layer take care of the swapping
* miscellaneous minor code cleanups and style fixes

Commit 9b8c69243 (since reverted) broke the ability to boot the kernel
as the value returned by unassigned_mem_read returned non-zero and left
the kernel looping forever waiting for it to change (see
integrator_led_set in the kernel code).
Relying on a varying implementation detail is incorrect anyway so this
introduces a basic stub of a memory region for the debug/LED section
on the integrator board.

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.

Now that ARMCPU is a subclass of DeviceState, we can make the
CPU's inbound IRQ and FIQ lines be simply gpio lines, which
means we can remove the odd arm_pic shim.
We retain the arm_pic_init_cpu() function as a backwards
compatibility shim layer so we can convert the board models
to get the IRQ and FIQ lines directly from the ARMCPU
object one at a time.
