KVM: arm/arm64: vgic-new: Add GICv3 MMIO handling framework
Create a new file called vgic-mmio-v3.c and describe the GICv3 distributor and redistributor registers there. This adds a special macro to deal with the split of SGI/PPI in the redistributor and SPIs in the distributor, which allows us to reuse the existing GICv2 handlers for those registers which are compatible. Also we provide a function to deal with the registration of the two separate redistributor frames per VCPU.
