Currently the dmic check code supports only devices with 2 or 4 dmics. With other dmic counts the function will return 0. Lately we've seen devices with only 1 dmic thus enable also configurations with 1, and possibly 3, dmics. Add also topology postfix -1ch and -3ch for new dmic configuration.

Currently the dmic check code supports only devices with 2 or 4 dmics.
With other dmic counts the function will return 0. Lately we've seen
devices with only 1 dmic thus enable also configurations with 1 dmic.
Add also topology postfix -1ch for 1 dmic configuration. It is possible
to use -2ch topology with 1 dmic and get "dual mono" stream, but if true
mono is required we need to have separate topology.
