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.
