backlight: Remove notifier
backlight_register_notifier and backlight_unregister_notifier have been unused since commit 6cb634d0dc85 ("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.
