drm/i915: remove unused config DRM_I915_UNSTABLE

Essentially this is a revert of commit d9d54a530a70 ("drm/i915: Put
future HW and their uAPIs under STAGING & BROKEN").

We currently have no users for this config option. The last one was
removed in commit 8c26491f5853 ("drm/i915: Kill the fake lmem
support"). Drop it altogether; it's easy enough to resurrect if need
arises.
