Dr. David Alan Gilbert 5461f3fd74 backlight: Remove notifier 
backlight_register_notifier and backlight_unregister_notifier have
been unused since commit 6cb634d0dc ("ACPI: video: Remove code to
unregister acpi_video backlight when a native backlight registers")

With those not being called, it means that the backlight_notifier
list is always empty.

Remove the functions, the list itself and the enum used in the
notifications.
