drm/msm: async commit support
Now that flush/wait/complete is decoupled from the "synchronous" part of
atomic commit_tail(), add support to defer flush to a timer that expires
shortly before vblank for async commits. In this way, multiple atomic
commits (for example, cursor updates) can be coalesced into a single
flush at the end of the frame.
v2: don't hold lock over ->wait_flush(), to avoid locking interaction
that was causing fps drop when combining page flips or non-async
atomic commits and lots of legacy cursor updates
