    drm/xe: Update GuC/HuC firmware autoselect logic
    
    Update the logic to autoselect GuC/HuC for the platforms with the
    following improvements:
    
    - Document what is the firmware file that is expected to be
      loaded and what is checked from blob headers
    
    - When the platform is under force-probe it's desired to enforce
      the full-version requirement so the correct firmware is used
      before widespread adoption and backward-compatibility
      commitments
    
    - Directory from which we expect firmware blobs to be available in
      upstream linux-firmware repository depends on the platform: for
      the ones supported by i915 it uses the i915/ directory, but the ones
      expected to be supported by xe, it's on the xe/ directory. This
      means that for platforms in the intersection, the firmware is
      loaded from a different directory, but that is not much important
      in the firmware repo and it avoids firmware duplication.
    
    - Make the table with the firmware definitions clearly state the
      versions being expected. Now with macros to select the version it's
      possible to choose between full-version/major-version for GuC and
      full-version/no-version for HuC. These are similar to the macros used
      in i915, but implemented in a slightly different way to avoid
      duplicating the macros for each firmware/type and functionality,
      besides adding the support for different directories.
    
    - There is no check added regarding force-probe since xe should
      reuse the same firmware files published for i915 for past
      platforms. This can be improved later with additional
      kunit checking against a hardcoded list of platforms that
      falls in this category.
    
    - As mentioned in the TODO, the major version fallback was not
      implemented before as currently each platform only supports one
      major. That can be easily added later.
    
    - GuC version for MTL and PVC were updated to 70.6.4, using the exact
      full version, while the
    
    After this the GuC firmware used by PVC changes to pvc_guc_70.5.2.bin
    since it's using a file not published yet.
