The set_channel_map() implementation in q6apm-lpass-dais driver was
copying older pre-Audioreach code from q6afe-dai driver, but not really
using it.  The code sets active channel mask based on passed channel
mapping, but Audioreach code does not use that mask ever.  Audioreach
module configuration does have on the other hand proper channel mapping
field, which should supersed that active channel mask.

Drop the unused active channel mask and implement proper mapping of
channels in q6apm-lpass-dais driver.

Changes in v2:
1. Entirely replaced - now channel mapping is implemented in
   q6apm-lpass-dais.
