Arvind Ram PrakashandJidong Sun 72f26f182f fix(cpus): workaround for Neoverse-V2 erratum 3701771 ...

Neoverse-V2 erratum 3701771 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.

The mitigation is implemented in commit 7455cd172 and this patch should be applied on top of it.
