Implement support to save/restore the ARM KVM VGIC state from the
kernel. The basic appraoch is to transfer state from the in-kernel VGIC
to the emulated arm-gic state representation and let the standard QEMU
vmstate save/restore handle saving the arm-gic state. Restore works by
reversing the process.
The first patches adds missing features and fixes issues with the
arm-gic implementation in qemu in preparation for the actual
save/restore logic.
The patches depend on the device control patch series sent out earlier,
which can also be found here:
git://git.linaro.org/people/cdall/qemu-arm.git migration/device-ctrl-v3
The whole patch series based on top of the above can be found here:

Changelog [v3]:
- Changes are described in the individual patches
- New patch that renames GIC_..._TRIGGER to GIC_..._EDGE_TRIGGER
- New patch to keep track of software writing to SPENDR and CPENDR
registers.
- New patch that fixes not clearing the pending state for an asserted
level-triggered interrupt on ACK
- Separate patch for the GICC_APRn state
Changelog [v2]:
- Changes are described in the individual patches
- VMState additions has been split into a separate patch
