MIPS: Probe guest MVH
Probe for availablility of M{T,F}HC0 instructions used with e.g. XPA in the VZ guest context, and make it available via cpu_guest_has_mvh. This will be helpful in properly emulating the MAAR registers in KVM for MIPS VZ. Signed-off-by:James Hogan <james.hogan@imgtec.com> Acked-by:
