fix(cpus): workaround for Cortex-A720-AE erratum 3699562

Cortex-A720-AE erratum 3699562 that applies to r0p0 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.
