ACPI: video: Add force_vendor quirk for Sony Vaio PCG-FRV35
The Sony Vaio PCG-FRV35 advertises both native and vendor backlight control interfaces. With the upcoming changes to prefer native over vendor acpi_video_get_backlight_type() will start returning native on these laptops. But the native radeon_bl0 interface does not work, where as the sony vendor interface does work. Add a quirk to force use of the vendor interface.
