drivers/video/backlight/apple_bl.c: include header for exported symbol prototypes

Include the header to pickup the exported symbol prototype.

  warning: symbol 'apple_bl_register' was not declared. Should it be static?
  warning: symbol 'apple_bl_unregister' was not declared. Should it be static?
