ACPI: video: Add dev argument for backlight_device_register

This patch set adds generic abstract layer support for acpi video driver to
have generic user interface to control backlight and output switch control by
leveraging the existing backlight sysfs class driver, and by adding a new
video output sysfs class driver.

This patch:

Add dev argument for backlight_device_register to link the class device to
real device object.  The platform specific driver should find a way to get the
real device object for their video device.
