[0/3] drm/xe: Update GuC/HuC firmware autoselection

Message

This re-aligns the xe driver with the upstream guidelines
(https://docs.kernel.org/driver-api/firmware/firmware-usage-guidelines.html?highlight=firmware+guideline)
and document the table used for it so it's easier to understand the
policy in place. Justification for the changes, including the exception
made in the guideline under "If the kernel support for the hardware is
normally inactive, or the hardware isn’t available for public
consumption, this can be ignored" is in the third commit.

Tested on Tigerlake, including some firmware renames to check if the
minor fallback works properly.
