I couldn't find any pictures online that show an analog audio output
(typically a 3.5mm socket).
Can you confirm that this is really present?

If there's no analog audio in/out then this section can be cleaned up

question to Neil: since we know that there's two board variants out
there (with different wifi chipsets) - are dt overlays down the road
enough (to enable Bluetooth / wifi - depending on the chipset or board
revision) or do we need to split the whole .dts?
