drm/amd/display: Detach backlight from stream
[Why] Backlight is conceptually a property of links, not streams. All backlight programming is done on links, but there is a stream property bl_pwm_level that is used to restore backlight on dpms on and s3 resume. This is unnecessary, as backlight is already restored by hardware with no driver intervention. [How] Remove bl_pwm_level, and the stream argument to set_backlight Signed-off-by:David Francis <David.Francis@amd.com> Reviewed-by:
