[PATCH 0/5] Workaround fixes, improvements, additions

[Tvrtko Ursulin]

A few things here.

0001:
I think per engine GT workarounds are broken. None apply since engines are not
set up yet.

0002-003:
I did a small audit of i915 vs xe workarounds and tunings with focus on ADL-P
and found some deltas. But without access to the internal database and even
up to date PRMs it is required if someone double checks the two.

Motivation being that there is some interest to make xe work on ADL-P as good as
possible.

0004:
With the split between workarounds and tunings it feels useful to expose the
list of latter in debugfs too.

0005:
Sadly there is still a mix of runtime vs static workarounds/tunings (so not
everything can be listed in debufs in a nice forma), some of
which look unavoidable such as MOCS and bits in
xe_hw_engine_setup_default_lrc_state.

But I thought on general it would be good to move everything that doesn't need
to be on those smaller sprinkled around lists to the central ones in
xe_workarounds.c/xe_tuning.c. It consolidates and adds visibility in debugfs.

Although again, it is still not perfect and maybe I missed some other reason
those I moved were where they were.
