KVM: arm64: vgic-v3: Simplify initial GICv3 configuration sampling

Browse source

Now that we have our magic inline helper for ICH_VTR_EL2, we can
get rid of the hack that was reporting a combination of that
register and of the indication of the CPU interface supporting
GICv2 compatibility. We now only report the latter.

As a small benefit, GICv5 is not involved in this stuff anymore,
since it never has GICv2 compatibility..
