Interesting. I would have expected that to pop up in dtbs_check, but
it does not for some reason. I will fix it for all usb2phy instances
in rk3588.

The above follows everything from [0], which does not specify an
order for the "standard/common  properties". For those this follows
the order of existing usb2phy nodes. Did I miss any other new
Documentation?
