Should be tcon0 -- tcon0 on A83T has only channel 0 and tcon1 has only
channel 1.

Since the capability of mixer0 and mixer1 are different (smart
backlight, write-back, VEP of the VI channel and extra UI
channels), I suggest to use ID-specific compatibles here.

As I said, V3s has 2 VI channels, so it totally shouldn't share
config with A83T.
