ucm2: HDA - add support for Internal Mic

[GitHub pull_request - opened]

alsa-project/alsa-ucm-conf pull request #207 was opened from kasper93:

Simple patch to support also "Internal Mic".

Everything seems to be working fine after this change, except that I don't have "Internal Mic Jack", I'm lying there a little to set it as such. Everything switches nicely when connecting/disconnecting headphones mic. But there are two input devices to select and selection doesn't have effect. I believe when headphone mic is connected the internal one should be hidden, but there is no Jack and I don't know how to handle it properly. (It is marked as conflicting device with the other one though) Except this minor annoyance it is fine.
