...
Matter of taste. Match the prefix for everything else related to
steppings. No functional changes.

drm/i915: switch TGL and ADL to the new stepping scheme
...
This changes the way revids not present in the array are handled:
- For gaps in the array, the next present revid is used.
- For revids beyond the array, the new STEP_FUTURE is used instead of
the last revid in the array.
In both cases, we'll get debug logging of what's going on.

drm/i915: switch KBL to the new stepping scheme
...
Add new symbolic names for revision ids, and convert KBL revids to use
them via the new stepping check macros.
This also fixes theoretical out of bounds access to kbl_revids array.

drm/i915: add new helpers for accessing stepping info
...
Add new runtime info field for stepping. Add new helpers for accessing
them. As we'll be switching platforms over to the new scheme
incrementally, check for non-initialized steppings.
In case a platform does not have separate display and gt steppings, it's
okay to use a common shorthand. However, in this case the display
stepping must not be initialized, and gt stepping is the single point of
truth.
