powerpc/hv-24x7: Fix pvr check when setting interface version

Commit ec3eb9d941a9 ("powerpc/perf: Use PVR rather than
oprofile field to determine CPU version") added usage
of pvr value instead of oprofile field to determine the
platform. In hv-24x7 pmu driver code, pvr check uses PVR_POWER8
when assigning the interface version for power8 platform.
But power8 can also have other pvr values like PVR_POWER8E and
PVR_POWER8NVL. Hence the interface version won't be set
properly incase of PVR_POWER8E and PVR_POWER8NVL.
Fix this issue by adding the checks for PVR_POWER8E and
PVR_POWER8NVL as well.
