All outputs have a 1:1 relationship between connectors and encoders
and the driver is relying on the atomic helpers: we can drop the custom
->best_encoder() implementations and let the core call
drm_atomic_helper_best_encoder() for us.

atomic_flush seems to be the right place, right after we commit the
plane updates. Again use the fullproof version, since the pipe might
be off.

No dev->struct_mutex anywhere to be seen.

Now that we have support for the composite output, we can start adding new
supported standards. Start with PAL, and we will add other eventually.

Some Allwinner SoCs have an IP called the TV encoder that is used to output
composite and VGA signals. In such a case, we need to use the second TCON
channel.
Add support for that TV encoder.

One of the A10 display pipeline possible output is an RGB interface to
drive LCD panels directly. This is done through the first channel of the
TCON that will output our video signals directly.

The Allwinner A10 and subsequent SoCs share the same display pipeline, with
variations in the number of controllers (1 or 2), or the presence or not of
some output (HDMI, TV, VGA) or not.
Add a driver with a limited set of features for now, and we will hopefully
support all of them eventually
