KVM: arm64: Reject the GICv5 CPU interface hypercalls under pKVM
__vgic_v5_save_apr() and __vgic_v5_restore_vmcr_apr() remain callable
once pKVM has finalised. pKVM never registers a GICv5 vgic, so neither
has a valid caller in protected mode, and on a GICv3 machine both reach
a register that is UNDEFINED at EL2 and panic the hypervisor.
Move both into the band the dispatcher rejects once pKVM has finalised.
[maz: Dropped hyp-main.c changes]
