After adding jack-detect support we have 3 microphone input switches: "Microphone 1", "Microphone 2" and "Headset Mic". But the ES8316 has only 2 microphone inputs.
In the app-note explaining how to use the codec and on the 3 boards I have one input is used for an internal microphone and one for the headset microphone. On the 2 CHT boards I have the internal mic is on on MIC1 and the headset mic is on MIC2, on the BYTCR board I have it is the other way around.
This commit replaces the 2 "Microphone 1" and "Microphone 2" input switches with a single "Internal Mic" switch and adds support for selecting either possible input mapping.
