drm: bridge: ldb: add support for using channel 1 only 
The LDB driver currently checks whether dual mode is used, otherwise it
assumes only channel 0 is in use. Add support for using only channel 1. In
device tree terms, this means linking port 2 only.

Doing this cleanly requires changing the logic of the probe functions from
this:

 1. use of_graph_get_remote_node() on port 1 to find the panel
 2. use drm_of_lvds_get_dual_link_pixel_order() to detect dual mode

to this:

 1. use of_graph_get_remote_node() twice to find remote ports
 2. reuse the result of the above to know whether each channel is enabled
    and to find the panel
 3. if (both channels as enabled)
        use drm_of_lvds_get_dual_link_pixel_order() to detect dual mode

Also add a dev_dbg() to log the detected mode and log an error in case no
panel was found (no channel enabled).
