This commit also removes various obsolete pr_xxx messages related to backlight interface selection. These are obsolete because they assume there is only a vendor or acpi backlight driver and no other choice. Also they are not necessary, if the user wants to know which backlight interfaces are registered a simple "ls /sys/class/backlight" suffices.
