Alex Deucher 90d239cc53 drm/amd/display: Fix DCE LVDS handling 
LVDS does not use an HPD pin so it may be invalid.  Handle
this case correctly in link encoder creation.

Fixes: 7c8fb3b8e9 ("drm/amd/display: Add hpd_source index check for DCE60/80/100/110/112/120 link encoders")
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/5012
