arm64: cpufeature: Detect HCR_EL2.NV1 being RES0
A variant of FEAT_E2H0 not being implemented exists in the form of
HCR_EL2.E2H being RES1 *and* HCR_EL2.NV1 being RES0 (indicating that
only VHE is supported on the host and nested guests).
Add the necessary infrastructure for this new CPU capability.
