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().
