drm/xe/pmu: Add GT C6 events
Provide a PMU interface for GT C6 residency counters. The interface is
similar to the one available for i915, but gt is passed in the config
when creating the event.
Sample usage and output:
$ perf list | grep gt-c6
xe_0000_00_02.0/gt-c6-residency/ [Kernel PMU event]
$ tail /sys/bus/event_source/devices/xe_0000_00_02.0/events/gt-c6-residency*
==> /sys/bus/event_source/devices/xe_0000_00_02.0/events/gt-c6-residency <==
event=0x01
==> /sys/bus/event_source/devices/xe_0000_00_02.0/events/gt-c6-residency.unit <==
ms
$ perf stat -e xe_0000_00_02.0/gt-c6-residency,gt=0/ -I1000
# time counts unit events
