Subject: drm/i915/rpl-s: Add stepping info
Git-commit: 8295524a2d5550b56e800ac779a183b7f4d8c33c
Patch-mainline: v5.18-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
Add stepping-substepping info in
accordance to BSpec changes.
Though it looks weird, the revision ID
for the newer stepping is indeed backwards
and is in accordance to the spec.
v2: Rearrange the platforms in logical order (Matt)
Bspec: 53655
