With MTL, frequency and rc6 counters are specific to a gt. Export these
counters via gt-specific events to the user space.

v2: Remove aggregation support from kernel
v3: Review comments (Ashutosh, Tvrtko)
v4:
- Include R-b for 6/6
- Add Test-with
- Fix versioning info in cover letter
v5:
- Include "drm/i915/pmu: Change bitmask of enabled events to u32"
