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.
v3: upgrade dbg to warn on unknown revid (José)
v2: Rename stepping->step
