fix(cpus): workaround for Neoverse-V3 erratum 3701767
Neoverse-V3 erratum 3701767 that applies to r0p0, r0p1, r0p2 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.
