KVM: PPC: Introduce FPR/VR accessor functions
Introduce accessor functions for floating point and vector registers
like the ones that exist for GPRs. Use these to replace the existing FPR
and VR accessor macros.
This will be important later for Nested APIv2 support which requires
additional functionality for accessing and modifying VCPU state.
