fix(cpus): workaround for Cortex-A725 erratum 3699564

Cortex-A725 erratum 3699564 that applies to r0p0, r0p1 and is
fixed in r0p2.

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.
