KVM: arm64: vgic-v3: Add ICV_IAR1_EL1 handler

Browse source

Add a handler for reading the guest's view of the ICC_IAR1_EL1
register. This involves finding the highest priority Group-1
interrupt, checking against both PMR and the active group
priority, activating the interrupt and setting the group
priority as active.
