drm/amd/display: Take emulated dc_sink into account for HDCP
[Why]
While updating the config of hdcp, we use the sink_singal type of the
dc_sink to decide the HDCP operation mode. However, it doesn't consider
the case when the sink is a emulated one.
[How]
Take dc_em_sink into account while updating HDCP config.
