msm: mdss: Correct element name for dtsi parsing

Color order was mistakenly updated without the qcom,
prefix, so the dtsi entry will have no effect.
Change updates the parse function so field will
be parsed correctly.

msm: mdss: clean up overlay resources properly when display is off

When display is turned off, the clocks are already turned off and
unprepared.  Earlier, when unsetting the overlay resource, we were
trying to re-enable the unprepared clocks.

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.
