Now that we have hooks to enable the atomic plane helpers, we can use
the plane helpers for our .update_plane() and .disable_plane()
entrypoints.

Even though we'd already refactored our plane handling code into
check/commit, we still have to rework some of that logic here as we make
the transition.  The atomic plane helpers now call prepare_fb/cleanup_fb
for us, so note the following:
 - 'commit' should not longer unpin the old object; the cleanup_fb will
   take care of this for us
 - prepare_fb only gets called when we actually have an fb, so the
   internal 'disable' code needs to update frontbuffer tracking
 - the cursor plane code never had 'prepare' code separated from its
   'commit' function, so a lot of the cursor's 'commit' needs to be
   dropped since prepare_fb already does it for us
 - with all the pinning work removed from cursor commit, it can no
   longer fail and should return void rather than int

So I'm now wondering where all this code is disappearing into?

Anyway this conflicts pretty harshly with Gutavo's pending patches. I
think at least the particular patch touching this had the r-b already
(apart from a stale bo unre left behind, which can easily be fixed up
when applying the patch).

So I would like to get Gustavo's patches in first, especially as they
move the code already to the right direction. We also have bugs in the
current code that need to fixed. Gustavo's patches came close, but not
quite there IIRC. So I think it would be nice to get that stuff done
first, and then toss this atomic stuff on top.
