drm/i915: Introduce G12 subplatform of DG2
Another fork of the DG2 design has appeared, known as "DG2-G12;" let's add it as a new subplatform. As with G11, the GT stepping resets back to A0 (so a DG2-G12 A0 is similar, but not identical, to a DG2-G10 C0) but the display steppings continue to use the same numbering scheme as G10 and G11. Some existing DG2 workarounds are starting to be extended to the DG2-G12 subplatform. So far only workarounds that were "permanent" for both DG2-G10 and DG2-G11 have been tagged for DG2-G12, but more stepping-specific workarounds are likely to show up in the future.
