Merge series "ASoC: qdsp6: add gapless compressed audio support" from Srinivas Kandagatla <srinivas.kandagatla@linaro.org>:

This patchset adds gapless compressed audio support on q6asm.
Gapless on q6asm is implemented using 2 streams in a single asm session.

First few patches are enhacements done to q6asm interface to allow
stream id per each command, gapless flags and silence meta data.
Along with this there are few trivial changes which I thought are necessary!
Last patch implements copy callback to allow finer control over buffer offsets,
specially in partial drain cases.

This patchset is tested on RB3 aka DB845c platform.

Thanks,
srini
