fix(cpus): workaround for Cortex-X925 erratum 3701747
Cortex-X925 erratum 3701747 that applies to r0p0, r0p1 and is still
Open.
The workaround is for EL3 software that performs context save/restore
on a change of Security state to use a value of SCR_EL3.NS when
accessing ICH_VMCR_EL2 that reflects the Security state that owns the
data being saved or restored.
