acpi: Remove sysfs_create_link from video driver
The acpi video driver attempts to explicitly create a sysfs link between the acpi device and the associated PCI device. However, we're now also doing this from the backlight core, which means that we get a backtrace caused by a duplicate file. Remove the code and leave it up to the backlight core.
