arm64: KVM: vgic-v3: Avoid accessing ICH registers
Just like on GICv2, we're a bit hammer-happy with GICv3, and access them more often than we should. Adopt a policy similar to what we do for GICv2, only save/restoring the minimal set of registers. As we don't access the registers linearly anymore (we may skip some), the convoluted accessors become slightly simpler, and we can drop the ugly indexing macro that tended to confuse the reviewers.
