Some devices using the NAU8824 have only one speaker. To still have things working properly this requires the left + right channels to both be mixed to the left speaker output.
This mixer setup is done by userspace based on UCM profiles. But this requires userspace to know that there is a mono-speaker. Add a helper function (for the machine driver) to get a components string providing this info.
This is done inside the codec driver because the codec driver already has a DMI quirk table.
