The TVP5150 DT bindings specify a single output port (port 0) that
corresponds to the video output pad (pad 1, DEMOD_PAD_VID_OUT).

I'm trying to get this to work with a TVP5150 analog TV decoder, and the
first problem is that this device doesn't have pad 0 as its single
output pad. Instead, as a MEDIA_ENT_F_ATV_DECODER entity, it has for
pads (input, video out, vbi out, audio out), and video out is pad 1,
whereas the device tree only defines a single port (0).
