AMD Parmer: change DdiList to ConnectorTypeDP to support DP and HDMI

This patch is based on >>AMD Thatcher: ConnectorTypeDP supports both DP and HDMI<< (I23cf1c6) [1]
    I tested by DP monitor and HDMI monitor connected by passive DP->HDMI adapter.
    Video and audio are OK. Hot plugging is also supported.
