Increase the maximum number of GIC interrupts for a9mp and a11mp to 1020,
and create a configurable property for each defaulting to 96 and 64
(respectively) so that device modelers can set the value appropriately
for their SoC. Other ARM processors also set their maximum number of
used IRQs appropriately.

Set the maximum theoretical number of GIC interrupts to 1020 and
update the save/restore code to only use the appropriate number for
each SoC.

Based on the implementation from Hector Martin <hector@marcansoft.com>

Hectors's implementation completely sidestepped the qemu usb system and
used libusb directly for usb device pass through.  So I've ripped out
the libusb bits (or left them in disabled, as reference for further
coding) and hooked up the qemu subsystem instead.  That work is not
complete yet though, partly due to limitations of the qemu usb
subsystem.  Nevertheless I think it is better to continue development
in-tree, especially as the qemu usb bits need a bunch of improvements
too for decent usb 3.0 support.

Current state:
  - usb-storage emulation should work ok.
  - Devices which need constant polling (HID emulation like usb-tablet)
    are known to not work.
  - ISO xfers are not implemented yet.
  - superspeed ports are not implemented yet.
  - usb pass-through is completely untested so far.

Breakage introduced by me when ammending a previous patch, sorry.

The secondary CPU bootloader in arm_boot.c holds secondary CPUs in a
pen until the primary CPU releases them. Make boards specify the
address to be polled to determine whether to leave the pen (it was
previously hardcoded to 0x10000030, which is a Versatile Express/
Realview specific system register address).

QEMU does have a "scsi" option (to be used like -device
virtio-blk-pci,drive=foo,scsi=off).  However, it only
masks the feature bit, and does not reject the command
if a malicious guest disregards the feature bits and
issues a request.

Without this patch, using scsi=off does not protect you
from CVE-2011-4127.
