alsa: Allow to augment ucm port properties

Browse source 
Since UCM doesn't perform the path lookups of alsa-mixer all UCM devices
fall back to the card's properties for e.g. icons and hence usually show
the `audio-card` icon for all ports giving a confusing UI to users as
all ports show the same icon.

As ucm names are pretty standard augment some common port names with
icons.
