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: Harry Wentland <Harry.Wentland@amd.com> Acked-by: Anthony Koo <Anthony.Koo@amd.com> Acked-by: Leo Li <sunpeng.li@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
