fix(cpus): workaround for Neoverse-N3 erratum 3699563

Neoverse-N3 erratum 3699563 that applies to r0p0 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.
