Subject: [PATCH v3 08/10] ASoC: q6asm-dai: prepare set params to accept profile change
rearrange code so that it will be easy to change the codec
profile at runtime. This means moving exiting set_params
to an internal wrapper which can be called when codec
profile changes.
This is also preparing the code for easy to use in gapless cases.
