drm/bridge: Handle unsupported panelsopenembedded-qcom-dragonboard845c-20.11openembedded-qcom-dragonboard410c-20.11debian-qcom-dragonboard845c-20.11debian-qcom-dragonboard410c-20.11
Some panels are currently supported by lt9611, but not by the display itself.
This causes issues where a mode unsupported by the display driver is picked
by the bridge.
