drm/i915/dg2: Drop pre-production GT workarounds
DG2 first production steppings were C0 (for DG2-G10), B1 (for DG2-G11),
and A1 (for DG2-G12). Several workarounds that apply onto to
pre-production hardware can be dropped. Furthermore, several
workarounds that apply to all production steppings can have their
conditions simplified to no longer check the GT stepping.
v2:
- Keep Wa_16011777198 in place for now; it will be removed separately
in a follow-up patch to keep review easier.
