drm/xe: Always log GuC/HuC firmware versions

When debugging issues related to GuC/HuC, it's important to know what is
the firmware version being used. The version from the filename can't be
relied upon, also because it normally only contains the major version
(except for the ones under experimental support).

Log the version from the blob after reading the CSS header. Example:

	xe 0000:03:00.0: [drm] Using GuC firmware (70.5) from i915/dg2_guc_70.bin
