cceb084905 drm/i915/perf: Enable bytes per clock reporting in OA
XEHPSDV and DG2 provide a way to configure bytes per clock vs commands
per clock reporting. Enable bytes per clock setting on enabling OA.

Bspec: 51762
Bspec: 52201

v2:
- Fix commit msg (Ashutosh)
- Fix checkpatch issues

v3:
- s/commands/bytes/ in code comment and commmit msg

a5c3a3cbf0 drm/i915/perf: Determine gen12 oa ctx offset at runtime
Some SKUs of same gen12 platform may have different oactxctrl
offsets. For gen12, determine oactxctrl offsets at runtime.

v2: (Lionel)
- Move MI definitions to intel_gpu_commands.h
- Ensure __find_reg_in_lri does read past context image size

v3: (Ashutosh)
- Drop unnecessary use of double underscores
- fix find_reg_in_lri
- Return error if oa context offset is U32_MAX
- Error out if oa_ctx_ctrl_offset does not find offset

v4: (Ashutosh)
- Warn on odd MI LRI_LEN
- Remove unnecessary check for valid_oactxctrl_offset
- Drop valid_oactxctrl_offset macro

v5: Drop unrelated comment

66a19a3a0e drm/i915/perf: Express OA register ranges with i915_range
Let's use 'struct i915_range' to express sets of b-counter and mux
registers in the perf code.  This makes the code more similar to how we
handle things like multicast register ranges, forcewake tables, shadow
tables, etc. and also lets us avoid needing symbolic register name
definitions for the various range end points.  With this change, many of
the OA register definitions are no longer used in the code, so we can
drop their #define's for simplicity.

v2:  Drop 'inline' from reg_in_range_table().  (Jani)

v3:  Split the first range in gen12_oa_mux_regs[] so that 0xd08 isn't
     whitelisted.  (Umesh)

2ef6d3bf42 drm/i915/perf: Move OA regs to their own header
The OA unit registers are only used by the perf code; move them to their
own header file.
