Govindraj Raja 050c4a38a3 fix(cpus): workaround for Cortex-A720 erratum 3699561 
Cortex-A720 erratum 3699561 that applies to all revisions <= r0p2
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.
