drm/amd/display: Use SIGNAL_TYPE_NONE in disable_output unless eDP
[WHY] Currently made a change where disable_output is called using signal_type. Using actual signal_type when calilng disable_output in power_down_encoders would make DP to HDMI dongle not light up on boot. As it would have signal_type SIGNAL_TYPE_DISPLAY_PORT. [HOW] Set signal_type to SIGNAL_TYPE_NONE unless it is eDP.
