The AMD CS5536's USB controllers are located at device 0F, functions 4
and 5. They're not found if only function 0 is checked. So if a device
exists at all, try all its functions. usb_controller_initialize() will
silently skip all device classes != 0C03.
(changed to continue to use 32bit accesses -pg)
