acpi_video_set_dmi_backlight_type() is troublesome because it may end up
getting called after other backlight drivers have already called
acpi_video_get_backlight_type() resulting in the other drivers
already being registered even though they should not.
Move all the acpi_backlight=[vendor|native] quirks from samsung-laptop to
drivers/acpi/video_detect.c .
Note the X360 -> acpi_backlight=native quirk is not moved because that
already was present in drivers/acpi/video_detect.c .
