Subject: drm/i915/dg1: Use revid->stepping tables
Git-commit: dae751f40c1913751bbdaed18224ff707f562319
Patch-mainline: v5.15-rc1
References: jsc#SLE-22601
Switch DG1 to use a revid->stepping table as we're trying to do on all
platforms going forward.
This removes the last use of IS_REVID() and REVID_FOREVER, so remove
those now-unused macros as well to prevent their accidental use on
future platforms.
v2:
- Use COMMON_STEP() macro in table. (Anusha)
