Kajol Jain 03f7c1d2a4 powerpc/hv-gpci: Fix hv_gpci event list 
Based on getPerfCountInfo v1.018 documentation, some of the
hv_gpci events were deprecated for platform firmware that
supports counter_info_version 0x8 or above.

Fix the hv_gpci event list by adding a new attribute group
called "hv_gpci_event_attrs_v6" and a "ENABLE_EVENTS_COUNTERINFO_V6"
macro to enable these events for platform firmware
that supports counter_info_version 0x6 or below. And assigning
the hv_gpci event list based on output counter info version
of underlying plaform.

Fixes: 97bf264018 ("powerpc/perf/hv-gpci: add the remaining gpci requests")
