KVM: arm64: Set ID_{AA64PFR0,PFR1}_EL1.GIC when GICv3 is configured

Drive the idreg fields indicating the presence of GICv3 directly from
the vgic code. This avoids having to do any sort of runtime clearing
of the idreg.

Fixes: 5cb57a1aff755 ("KVM: arm64: Zero ID_AA64PFR0_EL1.GIC when no GICv3 is presented to the guest")
