KVM: arm-vgic: Support CPU interface reg access
Implement support for the CPU interface register access driven by MMIO
address offsets from the CPU interface base address. Useful for user
space to support save/restore of the VGIC state.
This commit adds support only for the same logic as the current VGIC
support, and no more. For example, the active priority registers are
handled as RAZ/WI, just like setting priorities on the emulated
distributor.
