mainboard/google/reef: Add all DMIC endpoints

Browse Source 
Independent of Board DMIC configuration, add all DMIC points
i.e. add DMIC-1ch, DMIC-2ch, DMIC-4ch endpoints.

This allows flexibility to userspace to open capture devices as needed.
This is a temporary fix; once upper layers support choosing
particular channels from 4-ch PCM stream, we will limit exposing only
DMIC-4ch endpoint.

BUG=chrome-os-partner:60444
BRANCH=none
TEST=Verify All DMIC blobs are included
