drm/amd/display: take signal type from link 

[Why]
Signal is update to EDP when driver disable first encoder. The
following encoder using SIGNAL_TYPE_EDP to handle other
device. When encoder signal is HDMI, driver will detect it is dp
and release phy. It cause hw hang.

[How]
Take signal type from link->connector_signal.
