Currently, we are just using PMSCR_EL1 in the host for non VHE systems. We already have the {read,write}_sysreg_el*() accessors for accessing particular ELs' sysregs in the presence of VHE. Lets just define PMSCR_EL12 and start making use of it here which will access the right register on both VHE and non VHE systems. This change is required to add SPE guest support on VHE systems.
