These entries are board level routing. They should be done in the
board dts files. Unfortunately device tree does not provide a way
to "append" entries to properties, which means one has to copy all
the preceding entries as well.
Also, you are not adding the "Mic" and "Headset Mic" widgets. A33
uses simple-card, which means these connection/board level widgets
must be added using simple-audio-card,widgets.
