The RT5640 codec has 2 ADC-s which are caled the Stereo ADC and the Mono ADC (even though the mono ADC seems to be stereo too?). The Stereo ADC is connected to the AIF1 interface of the codec and the Mono ADC to the AIF2 interface.
Almost all X86 BYT/CHT design use the AIF1 interface, but a few models use the AIF2 interface. For this reason the IN?-InternalMic.conf bits not only select/enable the microphone input on the Stereo ADC, but also on the Mono ADC, so that the analog mic. inputs also work in devices using the AIF2 interface.
Before this commit DigitalMics.conf was only setting up the DMIC input on the Stereo ADC and not on the Mono ADC, causing DMIC1 to not work when connected over AIF2.
This commit adds selecting / enabling DMIC1 on the Mono ADC. This fixes the internal microphone not working on the Toshiba Encore WT10A.
Note that for devices which use the AIF1 interface this is a no-op since the AIF1 interface is not connected to anything, there is no complete chain so DAPM will not enable any of the elements in the chain.
