drm/amd/display: Cleanup uses of the analog flag
In the detect_link_and_local_sink() function, do not modify the
EDID capabilities of the display based on the connector. Instead,
respect the analog flag better and when the analog flag is set,
check that the connector indeed supports analog displays.
