You are not documenting the "ports" subnode(s).Please move the
individual ports definition under a ports subnode, mainly for two reasons:

- it makes it easy at the .dtsi level to have all ports disabled by default

- this makes you strictly conforming to the DSA binding for Ethernet
switches and this is good for consistency (both parsing code and just
representation).
