[PATCH 15/16] drm/amd/display: Add support for disconnected eDP streams

[Roman.Li at amd.com]

From: Harry VanZyllDeJong <hvanzyll at amd.com>

[Why]
eDP may not be connected to the GPU on driver start causing
fail enumeration.

[How]
Move the virtual signal type check before the eDP connector
signal check.
