drm/radeon: report disconnected for LVDS/eDP with PX if ddc fails
commit 13485794 upstream. If ddc fails, presumably the i2c mux (and hopefully the signal mux) are switched to the other GPU so don't fetch the edid from the vbios so that the connector reports disconnected. bug: https://bugzilla.opensuse.org/show_bug.cgi?id=904417 Signed-off-by:Alex Deucher <alexander.deucher@amd.com> Signed-off-by:
