ALSA: compress: Add support to send codec specific data
Codec specific metadata is sent only for first stream in gapless
playback. This causes incorrect configuration to be set for second
stream and distortions are observed due to framedrops in adsp.
Add support to send codec specific format during start of
next stream in gapless using set_next_track_param.
