backlight: Add Nvidia-based Apple Macbook Pro backlight driver
Nvidia-based Apple Macbook Pros don't appear to handle backlight control through the graphics card registers or ACPI, but instead trigger changes via SMI calls. This driver registers a generic backlight device that lets existing userspace deal with it. Code derived from Julien Blache's Pommed application.
