drm/i915: support low power watermarks on Ironlake
This patch actually makes the watermark code even uglier (if that's
possible), but has the advantage of sharing code between SNB and ILK at
least. Longer term we should refactor the watermark stuff into its own
file and clean it up now that we know how it's supposed to work.
Supporting WM2 on my Vaio reduced power consumption by around 0.5W, so
this patch is definitely worthwhile (though it also needs lots of test
coverage).
