KVM: arm64: nv: Add non-VHE-EL2->EL1 translation helpers

Browse source

Some EL2 system registers immediately affect the current execution
of the system, so we need to use their respective EL1 counterparts.
For this we need to define a mapping between the two. In general,
this only affects non-VHE guest hypervisors, as VHE system registers
are compatible with the EL1 counterparts.

These helpers will get used in subsequent patches.
