KVM: arm64: Don't map 'kvm_vgic_global_state' at EL2 with pKVM

Browse source

Now that 'kvm_vgic_global_state' is no longer needed for ICC_CTLR_EL1
emulation on machines with a broken SEIS implementation, drop the
pKVM hypervisor mapping of the page.

Note that kvm_vgic_global_state is still mapped in non-protected
hypervisor configurations (i.e. {n,h}VHE) through the rodata section
mapping.
