[PATCH 0/8] Refactor DC atomic commit and gamma

These patches are first steps of addressing some of the problems
in DC's atomic implementation. Please take a look and provide
feedback if possible. Our hope is that we can start setting a
direction on fixing up DC to do atomic correctly and lay the
groundwork for moving past the midlayer.

THe biggest patch here is Andrey's work to bring atomic_commit
in line with the atomic helpers instead of rolling our own. We
got atomic_commmit_tail now and things appear to work correctly
with this change. It allowed us to clean up some of the commit
code, but there's still a lot left.

The second important patch is fixing up our gamma implementation
and correct the use of crtc_set_property and atomic_set_properties.

Beyond that there's some minor cleanup and support patches for
the above change.
