KVM: arm64: Handle Apple M2 as not having HCR_EL2.NV1 implemented

Although the Apple M2 family of CPUs can have HCR_EL2.NV1 being
set and clear, with the change in trap behaviour being OK, they
explode spectacularily on an EL2 S1 page table using the nVHE
format. This is no good.

Let's pretend this HW doesn't have NV1, and move along.
