drm/amd/display: handle invalid connector indices
[Why]
The function to count the number of valid connectors does not
guarantee that the first n indices are valid, only that there
exist n valid indices. When invalid indices are present, this
results in later valid connectors being missed, as processing
would end after checking n indices.
[How]
- count valid indices separately from total indices examined
- add explicit definition of MAX_LINKS
