KVM: arm/arm64: Handle VGICv2 save/restore from the main VGIC code

Browse Source 
We can program the GICv2 hypervisor control interface logic directly
from the core vgic code and can instead do the save/restore directly
from the flush/sync functions, which can lead to a number of future
optimizations.
