[PATCH v6 2/6] drm/xe: add xe_device_wa infrastructure

[Matt Atwood]

There are some workarounds that must be appplied before gt init,
wa_15015404425 for example. Instead of sprinking them conditionally
throughout the driver as we did for i915 generate an oob.rules file
reusing the RTP infrastructure to make these easier to track.

v2: rename xe_soc_wa to xe_device_wa
v5: derive prefix from argument rather than hard coding the values.
v6: split out xe_gen-wa_oob changes
