... but this version includes a few other fixups to the OHCI code,
so please use it instead.
AT91: the two USB drivers (OHCI, UDC) got out of sync with various
usbcore and driver model PM updates; fix.
Also minor fixes to ohci: whitespace/style, MODULE_ALIAS so coldplug works
using /sys/.../modalias, and turn off _both_ clocks during suspend.
