[PATCH 3/3] KVM: arm64: Limit clearing of ID_{AA64PFR0,PFR1}_EL1.GIC to userspace irqchip

[Marc Zyngier]

Now that the idreg's GIC field is in sync with the irqchip, limit
the runtime clearing of these fields to the pathological case where
we do not have an in-kernel GIC.

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