drm/amd/display: fix multi edp panel instancing

Browse Source 
A previous fix attempted to correct mismatch between DM display
targets and dc panel instancing by only counting connected panels.
This behaviour breaks a feature, thus this is an alternative solution
that allows mapping display targets to dc links during mod_power_create.
