freqshift is only set for the data endpoint and syncmaxsize is only set for the sync endpoint. This results in a syncmaxsize of zero used in the proc output feedback format calculation, which gives a feedback format incorrectly shown as 8.16 for UAC2 devices.
As neither the data nor the sync endpoint gives all the relevant content, output the two combined.
Also remove the sync_endpoint "packet size" which is always zero and the sync_endpoint "momentary freq" which is constant.
Tested with UAC2 async and UAC1 adaptive, not tested with UAC1 async.
