[Intel-gfx] [PATCH v8 00/11] Add OAM support for MTL

[Umesh Nerlige Ramappa]

The OAM unit captures OA reports specific to the media engines. Add support to
program the OAM unit on media tile on MTL.

The OAM unit is selected by passing the class:instance of a media engine to perf
parameters. Corresponding UMD changes are posted to the igt-dev repo as part of
supporting the GPUvis tool.

v2: Incorporate review feedback (Jani, Ashutosh)
v3: Incorporate review feedback (Jani, Ashutosh)
v4: Incorporate review feedback (Ashutosh)
v5:
- Enforce paired engine-class and engine-instance configuration
- Include fix for Wa_14017512683

v6: Rebase to fix build failure
v7: Incorporate review comments
v8:
- Checkpatch fixes
- Initialize perf group irrespective of MC6 state (Ashutosh)
- Use group type check when opening perf stream (Ashutosh)
