ALSA: hda/realtek - change the location for one of two front microphones
On this Lenovo machine, there are two front mics, and both of them are assigned the same name "Mic", but pulseaudio can't support two mics with the same name, as a workaround, we change the location for one of them, then the driver will assign "Front Mic" and "Mic" for them.
