drm/amd/display: Fix passive dongle mistaken as active dongle in EDID emulation
[Why]
dongle_type is set during dongle connection but for passive dongles,
dongle_type is not set. If user starts with an active dongle and
then switches to a passive dongle, it will still report as an active
dongle. Trying to emulate the wrong connecter type results in display
not lighting up.
[How]
Set dpcd_caps.dongle_type for passive dongles in detect_dp().
