Include the header to pickup the exported symbol prototype.

Quiets the sparse warning:

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

[akpm@linux-foundation.org: fix resulting build error]
