drm/sun4i: tcon-top: Keep mixer routes distinct
Both mixer selectors reset to TCON 0. Selecting the same TCON for both
mixers causes black or corrupted output.
When a route would collide, park the other mixer on another described
TCON, or an unused selector if none exists.
Since the TCON index is now used as a shift, also reject negative
values.
Tested on Orange Pi 3 with TCON_LCD0 and TCON_TV0.
