ALSA: hda/realtek - change the location for one of two front microphones

commit f33f79f3d0e5caf04dd889cd7cf636261970f009 upstream.

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.
