Subject: drm/i915/glk: Use revid->stepping tables
Git-commit: 3dd22d46c7f6ddfb8c5e5d7c45649cd922bdd8cb
Patch-mainline: v5.15-rc1
References: jsc#SLE-22601
Switch GLK to use a revid->stepping table as we're trying to do on all
platforms going forward. Pre-production and placeholder revisions are
omitted.
Although nothing in the code is using the data from this table at the
moment, we expect some upcoming DMC patches to start utilizing it.
