arm64: KVM: Add VGIC device control for arm64
This fixes the build breakage introduced by
c07a0191ef2de1f9510f12d1f88e3b0b5cd8d66f and adds support for the device
control API and save/restore of the VGIC state for ARMv8.
The defines were simply missing from the arm64 header files and
uaccess.h must be implicitly imported from somewhere else on arm.
