Marc Zyngier b3265a1b2b KVM: arm64: set_id_regs: Allow GICv3 support to be set at runtime ...

set_id_regs creates a GIC3 guest when possible, and then proceeds
to write the ID registers as if they were not affected by the presence
of a GIC. As it turns out, ID_AA64PFR1_EL1 is the proof of the
contrary.

KVM now makes a point in exposing the GIC support to the guest,
no matter what userspace says (userspace such as QEMU is known to
write silly things at times).

Accommodate for this level of nonsense by teaching set_id_regs about
fields that are mutable, and only compare registers that have been
re-sanitised first.
