fix(cpus): workaround for Neoverse-N2 erratum 3701773

Neoverse-N2 erratum 3701773 that applies to r0p0, r0p1, r0p2 and r0p3
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.
