motorola-ghost: Fix rendering and add touchscreen support
The display is now able to render correctly with msm-fb-refresher. Touchscreen support was also added, but I'm not really sure that it needs calibration. I've tested all the weston examples and they all work perfectly.
Right now I'm trying to get osk-sdl to work, but it may be a little more difficult since the device framebuffer depth is 32-bit (checked via fbdebug), which is a bit odd since TWRP reports the value of 16 in fb0/bits_per_pixel.
