fix(rgb_lcd): relax the check for the data line GPIO

There are a bunch of cases you might want some pins not exposed.

Eg.

  * Reading say 8 bit data and outputting the top 5 bits, discarding the rest by not mapping those data pins to output pins

 * Not using hsync/vsync because sync data is embedded within the data bits for more timing flexibility (eg. interlacing).

 * Using the LCD module as a high speed parallel data output bus, with no need for sync/control pins.

Removing this validation makes these cases work.
