arm64: dts: ti: iot2050: Factor out arduino connector bits

A new variant is to be added which will not have a arduino connector
like the existing ones. Factor out all bits that are specific to this
connector.

The split is not perfect because wkup_gpio0 is defined based on what is
common to all variants having the connector, thus containing also
connector-unrelated information. But this is still cleaner than
replicating this node into all 4 variants.
