[PATCH v5 0/2] drm/xe: Add and refactor workarounds

[Aradhya Bhatia <aradhya.bhatia@intel.com>]

Hello,

This patch series adds the workarounds, Wa_16021333562, and Wa_14016712196.
It further refactors  Wa_18013179988, Wa_14015568240, Wa_1508761755, and
Wa_1509372804, to use the newer macro, XE_WA(), for OOB workarounds,
instead of selection based on platform labels.

Thanks,
Aradhya

Change Log:
V5:
  - Rename LRC_PPHWSP_SCRATCH_ADDR to LRC_PPHWSP_FLUSH_INVAL_SCRATCH_ADDR
    in the WA implementation, as the name has gotten updated in commit 
    f0c06677d110 ("drm/xe/pxp: Add VCS inline termination support"), in
    patch 1/2, as reported by Lucas De Marchi.
  - Move the Wa_14016712196 diff chunk above all the flags and calculations
    for better clarity in patch-1/2, as recommended by Lucas De Marchi.
  - Add R-b tags of Tejas Upadhyay in patch-1, and Lucas De Marchi in
    patch-2.

V4:
  - Combine Wa_16021333562 condition check with another workaround in
    patch-1, as suggested by Tejas Upadhyay.
  - Fix the offset value for the pipe control emit for Wa_14016712196 in
    patch-1, as suggested by Tejas Upadhyay.
  - Add Tejas Upadhyay's R-b tag for patch-2.

V3:
  - Fix the applicable Gfx platform ranges for WAs, in patches 1, and 2.
  - Add more WAs for refactoring in patch-2, and reword it accordingly.

V2:

    implementation as suggested by Lucas De Marchi.
  - Expand the ranges of Wa_16021333562 and Wa_14016712196 as per WA
