[v2,0/5] ASoC: qdsp6: add compress offload support

Message

This patchset adds support to very basic MP3 playback compress offload
support via QDSP ASM module.

Tested this patchset on DB410c with APQ8016 and DB820c with APQ8096 using
tinycompress library.

Adding other codec support should be trivial w.r.t qdsp6 side, however
there are other dependencies like compress UAPI header changes and
FastRPC which are being worked in parallel. Once ready will post them!

thanks,
srini
