ALSA: fireface: share PCM buffer size for both direction
This commit allows ALSA fireface driver to share PCM buffer size for
both capture and playback PCM substream. When AMDTP domain starts for
one of the PCM substream, buffer size of the PCM substream is stores to
AMDTP domain structure. Some AMDTP streams have already run with the
buffer size when another PCM substream starts, therefore the PCM
substream has a constraint to its buffer size.
