[Intel-gfx] [PATCH v2] drm/i915/pmu: Drop I915_ENGINE_SAMPLE_MAX from uapi headers

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

We have agreed during the engine classes discussion that fields marked as
non-ABI are better left out altogether from uapi headers.

v2: Use a local define for maintanability. (Chris Wilson)
