This should allow using ohci-platform from devicetree in various cases.
Specifically after this commit it can be used for the ohci controller found

Two minor nits: there should be no "0x" in the address part of the node name. And according to ePAPR [1], "the name of a node should be somewhat generic, reflecting the function of the device and not its precise programming model. If appropriate, the name should be one of the following choices:

- usb".
Same comments for "usb-ehci" binding.
You're right on both accounts, I'll do a v8 tomorrow, including a re-spin of the
