[Intel-gfx] [RESEND] drm/i915/rpl-s: Add stepping info

[Anusha Srivatsa]

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
