[PATCH v4 27/40] KVM: arm64: Prepare to handle deferred save/restore of ELR_EL1

ELR_EL1 is not used by a VHE host kernel and can be deferred, but we
need to rework the accesses to this register to access the latest value
depending on whether or not guest system registers are loaded on the CPU
or only reside in memory.
