I have thought about this over the weekend and I would keep the node name for
the codec as it is in the patch.
It is the common practice for audio and it also helps when reading the DT file
to quickly see the audio support on the board. We all use the 'sound' node
name for audio cards and when we use the name of the codec as node name we do
not need to look further in the dts file to see what is the codec in used (and
what/which cpu dai we are using). All this can be seen in the main sound
support node.
