KVM: arm64: Make RVBAR_EL2 accesses UNDEF

Browse source

We always expose a virtual CPU that has EL3 when NV is enabled,
irrespective of EL3 being actually implemented in HW.

Therefore, as per the architecture, RVBAR_EL2 must UNDEF, since
EL2 is not the highest implemented exception level. This is
consistent with RMR_EL2 also triggering an UNDEF.

Adjust the handling of RVBAR_EL2 accordingly.
