drm: Revert dma-fence annotations from omapdrm and tidss

Both omapdrm and tidss give quite similar lockdep warnings ever since
the "Annotate dma-fence critical section in commit path" patches.
I've tried to look at this, but I haven't gotten far with understanding
all this, and I feel that I'd need to really dive deep into the details
to understand all the locking dependencies relevant here.
With some git-log digging, I noticed this:
https://patchwork.freedesktop.org/patch/462170/
So maybe the "fix" is just to revert the patches. If yes, great, we can
apply the patches here. If not, not so great, and I'll just have to
start the diving =).
