[Intel-gfx] [PATCH 0/7] Minor revid/stepping and workaround cleanup

[Matt Roper]

PCI revision IDs don't always map to GT and display IP steppings in an
intuitive/sensible way.  On many of our recent platforms we've switched
to using revid->stepping lookup tables with the infrastructure in
intel_step.c to handle stepping lookups and comparisons.  Since it's
confusing to have some of our platforms using the new lookup tables and
some still using old revid comparisons, let's migrate all the old
platforms over to the table approach since that's what we want to
standardize on going forward.  The only place that revision ID's should
really get used directly now is when checking to see if we're running on
pre-production hardware.

Let's also take the opportunity to drop a bit of effectively dead code
in the workarounds file too.
