ps3fb: reorganize modedb handling
Reorganize modedb handling: - Reorder the video modes in ps3fb_modedb, for easier indexing using PS3AV_MODE_* numbers, - Introduce ps3fb_native_vmode(), to convert from native (PS3AV_MODE_*) mode numbers to struct fb_videomode *, - Rename and move ps3fb_default_mode() to ps3fb_vmode().
