Subject: * 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)
