We were using GRAPHICS_VER() to handle SKL_DFSM register, which means we
were not handling GLK correctly since that has GRAPHICS_VER == 9, but
DISPLAY_VER == 10. Switch the entire branch to check DISPLAY_VER
which makes it more in line with Bspec.
Even though the Bspec has an exception for RKL in
TGL_DFSM_PIPE_D_DISABLE, we don't have to do anything as the bit has
disable semantic and RKL doesn't have pipe D.
Bspec: 50075, 7548

As we begin applying XeHP and DG2 patches, the basic platform
definitions and macros (like IS_DG2()) will be needed in both
drm-intel-next and drm-intel-gt-next. Those initial definition patches
are applied to a topic branch and merged to both trees.

Besides the arch version returned by GRAPHICS_VER(), new platforms
contain a "release id" to make clear the difference from one platform to
another.
The release id number is not formally defined by hardware until future
platforms that will expose it via a new GMD_ID register. For the
platforms we support before that register becomes available we will set
the values in software and we can set them as we please. So the plan is
to set them so we can group different features under a single
GRAPHICS_VER_FULL() check.
After GMD_ID is used, the usefulness of a "full version check" will be
greatly reduced and will be mostly used for deciding workarounds and a
few code paths. So it makes sense to keep it as a separate field from
graphics_ver. Also, as a platform with `release == n` may be closer
feature-wise to `n - 2` than to `n - 1`, use the word "release" rather
than the more common "minor" for this
This is a mix of 2 independent changes: one by me and the other by Matt
Roper.
v2:
- Reword commit message to make it clearer why we don't call it
"minor" (Matt Roper and Tvrtko)
- Rename variables s/*_ver_release/*_rel/ and print them in a single
line formatted as {ver}.{rel:2} (Jani and Matt Roper)

(cherry picked from commit ca6374e267)
Signed-off-by: Matt Roper <matthew.d.roper@intel.com>
Workarounds are documented in the bspec with an exclusive upper bound
(i.e., a "fixed" stepping that no longer needs the workaround). This
makes our driver's use of an inclusive upper bound for stepping ranges
confusing; the differing notation between code and bspec makes it very
easy for mistakes to creep in.
Let's switch the upper bound of our IS_{GT,DISP}_STEP macros over to use
an exclusive upper bound like the bspec does. This also has the benefit
of helping make sure workarounds are properly handled for new minor
steppings that show up (e.g., an A1 between the A0 and B0 we already
knew about) --- if the new intermediate stepping pulls in hardware fixes
early, there will be an update to the workaround definition which lets
us know we need to change our code. If the new stepping does not pull a
hardware fix earlier, then the new stepping will already be captured
properly by the "[begin, fix)" range in the code.
We'll probably need to be extra vigilant in code review of new
workarounds for the near future to make sure developers notice the new
semantics of workaround bounds. But we just migrated a bunch of our
platforms from the IS_REVID bounds over to IS_{GT,DISP}_STEP, so people
are already adjusting to the new macros and now is a good time to make
this change too.

It also takes care of renaming the variable we assign to GRAPHICS_VER()
so to use "ver" rather than "gen".
