[PATCH] USB: au1200: EHCI and OHCI fixes

I received an DBAU1200 eval kit from AMD a few days ago and tried to
enable the USB2 port, but the current linux-2.6 GIT did not even
compile with CONFIG_SOC_1200, CONFIG_SOC_AU1X00, CONFIG_USB_EHCI and
CONFIG_USB_OHCI set.
Furthermore, in ehci-hcd.c, platform_driver_register() was called with
an improper argument of type 'struct device_driver *' which of course
ended up in a kernel oops. How could that ever have worked on your
machines?

Anyway, here's a trivial patch that makes the USB subsystem working
on my board for both OHCI and EHCI.
It also removes the /* FIXME use "struct platform_driver" */.
