2 mono speaker setup fixes:
1. Use the kernel's components string to check for a mono-speaker device when the board has a components string.
2. So far known nau8824 boards with a mono speaker where using the right speaker channel, which is unusual. Normally mono speaker setups use only the left speaker channel. The Cyberbook T116 tablet is a nau8824 based model, which indeed uses the left speaker channel for its single speaker.
Modify ucm2/codecs/nau8824/MonoSpeaker.conf to send a left+right channel mix to both speaker channels, so that things will work independent of which speaker channel is used for a mono setup.
