drm/i915/skl: Use revid->stepping tables
Switch SKL to use a revid->stepping table as we're trying to do on all
platforms going forward. Also drop the preproduction revisions and add
the newer steppings we hadn't already handled.
Note that SKL has a case where a newer revision ID corresponds to an
older GT/disp stepping (0x9 -> STEP_J0, 0xA -> STEP_I1). Also, the lack
of a revision ID 0x8 in the table is intentional and not an oversight.
We'll re-write the KBL-specific comment to make it clear that these kind
of quirks are expected.
v2:
- Since GT and display steppings are always identical on SKL use a
macro to set both values at once in a more readable manner. (Anusha)
- Drop preproduction steppings.
