Oleksandr Tymoshenko c344416ecd [rpi] Inherit framebuffer BPP value from the VideoCore firmware
Instead of using hardcoded bpp of 24, obtain current/configured value
from VideoCore. This solves certain problems with Xorg/Qt apps that
require bpp of 32 to work properly. The mode can be forced by setting
framebuffer_depth value in config.txt
