[Fix] Add new way to change brightness. [Test] After the fix is applied, there's a new backlight sysfs "nvidia_wmi_ec_backlight" can change the screen brightness. [Where problems could occur] The driver relies on BIOS to behave correctly. If the BIOS lies or has a bug, the new backlight interface will overtake other backlight interfaces. It's rather unlikely though.
