[Intel-xe] [PATCH v4 00/21] Dump + OOB workarounds

[Lucas De Marchi]

May the fourth be with the workarounds.
Fourth version of the OOB workarounds.

Previous version can be seen here:
https://lore.kernel.org/intel-xe/20230516221950.3512818-1-lucas.demarchi@intel.com/

Changes in v4:

  - All workarounds are now tracked per gt instead of per device. This
    helps supporting new platforms with different types of GTs

  - Split the last commit to be per (group of) workaround. Original
    intention was to just port the workarounds over to the new infra
    using the same conditions as was originally in the code. As
    demonstrated by v3 and the commits here, the conditions currently
    there can't be trusted much.

  - Add commit to fix build with M=drivers/gpu/drm/xe/ since it has a
    side-effect of not including the $(obj) in the include search path.

  - Properly convert Wa_14014475959 using IP versions. This is currently
    working for DG2, but I couldn't really test on MTL. We may want to
    postpone the last 2 commits to when xe is properly loading in MTL.

Using a DG2 platform for test:
	XE_DG2 G12 56b2:0001 dgfx:1 gfx:Xe_HPG (12.55) media:Xe_HPM (12.55) ...
	Stepping = (G:A1, M:A1, D:C0, B:**)

Eventually we may want to add a node in debugfs to consolidate the WAs
for all GTs, but that is not currently needed.
