drm/i915: Remove dead KMS encoder save/restore code.

瀏覽代碼 
This was brought over from UMS, and used for a while until we decided
that drm_helper_resume_force_mode was easier and more reliable, since
it didn't require duplicating all the code deleted here.  We just
forgot to delete all that junk for a while.
