drm/amd/display: Only poll analog connectors 



Analog connectors may be hot-plugged unlike other connector
types that don't support HPD.

Stop DRM from polling other connector types that don't
support HPD, such as eDP, LVDS, etc. These were wrongly
polled when analog connector support was added,
causing issues with the seamless boot process.
