msm: mdss: add retire fence support
Retire fence timeline should follow the actual panel vsync more closely.
For video mode the retire fence can be signaled along with the release
timeline with +1 offset, since this is signaled at vsync.
In case of command mode the panel vsync can be different from buffer
release timeline. To handle the command mode panel vsyncs better, create
a new timeline for the retire fence signaling.
