hw/intc/arm_gicv3: Add accessors for ICH_ system registers

Browse source 
The GICv3 virtualization interface includes system registers
accessible only to the hypervisor which form the control
interface for interrupt virtualization. Implement these
registers.

The function gicv3_cpuif_virt_update() which determines
whether it needs to signal vIRQ, vFIQ or a maintenance
interrupt is introduced here as a stub function -- its
implementation will be added in a subsequent commit.
