ACPI: video: Add force_vendor quirk for Panasonic Toughbook CF-18
The Panasonic Toughbook CF-18 advertises both native and vendor backlight control interfaces. But only the vendor one actually works. acpi_video_get_backlight_type() will pick the non working native backlight by default, add a quirk to select the working vendor backlight instead.
