Add support for ohci-platform instantiation from devicetree, including

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

+Generic MMIO OHCI controller
OHCI controller always uses MMIO, and likewise EHCI. You don't need to specifically mention it.
Right, I'm only using it here because it is also used in the compatible string.
+
+Required properties:
+- compatible : "mmio-ohci"
Likewise, it's not a good name. Why not call it "platform-ohci"?
Because, as you would have known had you read the entire thread, people objected
against exactly that name because the "platform" bus thing is a Linux invention,
and other operating systems don't use the platform nomenclature for non pci
busses.
Regards,
Hans
