LVDS and RGB interfaces are always connected to TCONs which have channel
0. It doesn't make sense to try to init them on TV TCONs.

Add a check if TCON has channel 0 before trying to init LVDS or RGB
interface.

Though I think at some point we could just have separate functions
to handle channel 0 and channel 1.
