The usb host controllers already come with an abstraction layer, e.g. there
is ehci-fsl.c, ehci-au1xxx.c and some more. All powerpc bases systems that
have the host controller on a local bus instead of PCI should use a common
driver for that, I believe one has already been posted some time ago,
but I'm not entirely sure about that.
As mentioned by Kumar Gala, we should eventually migrate over the users
of ehci-fsl to a new ehci-of, but getting rid of ehci-fsl means removing
all its users in arch/ppc first.
