ALSA: pcm: fix ELD constraints for (E)AC3, DTS(-HD) and MLP formats
The SADs of compressed formats contain the channel and sample rate info of the audio data inside the compressed stream, but when building constraints we must use the rates and channels used to transport the compressed streams. eg 48kHz 6ch EAC3 needs to be transmitted as a 2ch 192kHz stream. This patch fixes the constraints for the common AC3 and DTS formats, the constraints for the less common MPEG, DSD etc formats are copied directly from the info in the SADs as before as I don't have the specs and equipment to test those.
