ARM: gic-v3: Introduce 32-to-64-bit mappings for GICv3 cpu registers
vgic-v3 save/restore routines are written in such way that they map arm64 system register naming nicely, but it does not fit to arm world. To keep virt/kvm/arm/hyp/vgic-v3-sr.c untouched we create a mapping with a function for each register mapping the 32-bit to the 64-bit accessors. Please, note that 64-bit wide ICH_LR is split in two 32-bit halves (ICH_LR and ICH_LRC) accessed independently.
