drm/i915: Add debugfs entry to read/write next_seqno
This is needed for testing seqno wrapping. Be careful to not bump next_seqno
more than 0x7FFFFFFF at a time (between some handled requests) as
i915_seqno_passed() can't handle bigger difference in between.
v2: Address review comments from Chris Wilson.

unload again.]
