Read the ELD from the output pin to select the correct audio framing.
hdaa_audio_setup() reads the converter widget's ELD when choosing between
HDMI and DisplayPort audio infoframes. ELD is stored on the output pin,
so the converter has no ELD and the driver selects HDMI framing even
when the connected display uses DisplayPort.
