Renoir platform has onboard dmic + south bridge HD Audio endpoint
support.
For onboard Dmic, Audio endpoint name is populated as "Analog Input"
in Audio input devices.
How can we populate name as "Internal Mic" or "Dmic" in audio input
devices tab in sound settings?

It's question for pulseaudio. For the legacy ALSA code in PA, you need
to create profile, mixer path and udev rules. The probe mechanism used
in PA looks for the volume controls and path switches (kcontrol) API
to determine the device name. If not found, the generic name is used.
It's better to finish the UCM support for this hardware:

I just added a comment on the issues/30.
So far the biggest issue is how to make the ucm only apply to machines
with renoir audio and let those ucm not affect other machines.
