Either these should be common properties and documented in a common 
spot or they need vendor prefixes. They seem like they former to me 
(though 'sgmii-delay' would need to be more general and take a time).

I've managed to spin a subsequent revision which avoids the need for a
device tree change, based on comments similar to yours. I'll keep them
in mind should it become necessary to re-introduce the DT options.
