KVM: ARM: vgic: abstract VMCR access
Instead of directly messing with with the GICH_VMCR bits for the CPU interface save/restore code, add accessors that encode/decode the entire set of registers exposed by VMCR. Not the most efficient thing, but given that this code is only used by the save/restore code, performance is far from being critical.
