[SRU][Focal][OEM-5.6][Groovy][PATCH 1/1] UBUNTU: SAUCE: ASoC: SOF: intel: hda: support also devices with 1 and 3 dmics

[Hui Wang]

From: Jaska Uimonen <jaska.uimonen at linux.intel.com>

BugLink: https://bugs.launchpad.net/bugs/1891585

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.
