drm/amd/display: Add a backlight module option
There seem devices that don't work with the aux channel backlight
control. For allowing such users to test with the other backlight
control method, provide a new module option, aux_backlight, to specify
enabling or disabling the aux backport support explicitly. As
default, the aux support is detected by the hardware capability.
v2: make the backlight option generic in case we add future
backlight types (Alex)
