[v1,3/3] drm/i915/xelpg: Extend some workarounds/tuning to gfx version 12.74

Commit Message

Kalvala, Haridhar Dec. 21, 2023, 2:32 p.m. UTC

From: Matt Roper <[e-mail]>

Some of our existing Xe_LPG workarounds and tuning are also applicable
to the version 12.74 variant.  Extend the condition bounds accordingly.
Also fix the comment on Wa_14018575942 while we're at it.

v2: Extend some more workarounds (Harish)
