So this code is basically just working out which DSP core we
should be opening (at the moment this is fixed a DAI coresponds
to a particular DSP core). At the bottom of the function we call
wm_adsp_compr_open which will check that the firmware supports
compressed operation in the correct direction and will lock out
changes of firmware until compr_free is called.

Thanks,
Charles
