[Intel-xe] [PATCH 0/7] OOB workarounds

[Lucas De Marchi]

Continuation of the RFC https://patchwork.freedesktop.org/series/116365/

First 5 patches are drive-by trivial fixes that could be applied
regardless of the rest.

6th patch implements the logic for OOB workarounds and the last one
makes use of that in xe_guc.c

Changes from the RFC:

	- This concentrates on reporting just the active workarounds,
	  not all the workarounds implemented in the driver. That will
	  make more sense for a debugfs interface rather than the
	  previous dump

	- Instead of allowing a condition statement to be passed as
	  argument to the macro, migrate the macro to use he rtp rules.
	  Advantage here is that the rules can be executed not only on
	  the code path they are in, but also during initialization or
	  upon a debugfs call. This allows to report the "active"
	  workarounds without requiring that code path to be traversed.
	  Eventually the OOB workarounds may be changed to execute the
	  rules only on probe, saving an "active" bit in the device.

	  Limitation here is that the XE_WA() currently only supports
	  rules checking the device info.
