drm/amd/display: Skip DIG Check if Link is Virtual for Display Count

Browse Source 
[WHY]
Without a check for virtual links, every link's DIG was getting
checked for enabled or disabled. If link was virtual, since it
did not have a DIG, this would cause issues.

[HOW]
Skip DIG Enable check if link is virtual and add virtual link to
to display count.
