Bug Description

[Impact]
The dell-uart-backlight driver has been loaded, but the backlight is controller by graphics driver instead of scalar IC. The old way to determinate weather the driver should be loaded is not working anymore, since the behavior of scalar command, show firmware version, is not the same as old platforms.

[Fix]
Using more a reliable command, get_scalar_status, to check if scalar is in charge of the AIO backlight.
For the old platforms which don't have the new command, I add a list to list them all and use the old way to determinate the scalar IC.

[Test]
Verified on old and new Dell AIO platforms.

[Regression Potential]
Low. The quirk lists all old platforms which use the old way to check if scalar IC is in use. So, it won't change the behavior on old platforms, and apply the new method on new platforms.
