[PATCH v3 00/13] drm/xe: Add psmi support

[Lucas De Marchi <lucas.demarchi@intel.com>]

Add PSMI support to aid debugging. More information about PSMI is in the
first and second patches.

Expose the toggle to enable it via configfs, which allows to debug just
one of the possible cards attached.

The buffer allocation request is done via debugfs.

In order to apply WAs conditionally to using PSMI, a new
RTP match is also added.

The rest of the patches are improvements to our configfs integration
that I've been collecting while reviewing other semi-related patches.
