[RESEND][PATCH 1/2] dt-bindings: usb: add non-removable-ports hub property

[Mans Rullgard]

Add a non-removable-ports property that lists the hardwired downstream
ports of a hub.  Although hubs can provide this information, they are
not always configured correctly.  An alternate means of indicating this
for built-in USB devices is thus useful.
