* Onda VX767: fix some redundant files + add some missing functions for apps/ compilation (still needs keymap though).

* Add Onda VX767 SADC driver
* Unify Onda VX747(+) and Onda VX767 backlight driver
* Also be more consistent wrt file naming.
* Add speaker-onda_vx747.c to SOURCES (forgot to commit this)
