Many drivers (21 to be exact) create connectors that are always
connected (for instance to an LVDS or DSI panel). Instead of forcing
them to implement a dummy .detect() handler, make the callback optional
and consider the connector as always connected in that case.

These component_ops structures are only used as the second argument to
component_add and component_del, which are declared as const, so the
structures can be declared as const as well.
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@r disable optional_qualifier@
identifier i;
position p;
@@
static struct component_ops i@p = { ... };
@ok1@

component_add(e1,&i@p)

The result of the size command before the change is (arm):

The drm_mode_create call might return NULL in case of a failure, and the
current code doesn't check for that. Make sure it does.

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.

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.
