[RFC PATCH 8/9] dt: deps: dts: kirkwood: dockstar: add dependency ehci -> usb power regulator

[Alexander Holler]

This serves as an example how easy it is to fix an initialization order
if the order depends on the DT. No source code changes will be necessary.

If you look at the dependency graph for the dockstar, you will see that
there is no dependency between ehci and the usb power regulator. This
ends up with the fact that the regulator will be initialized after ehci.

Fix this by adding one dependency to the .dts.
