Hi Peter,

This looks much better than the first version. I have some remaining comments for
how it could be simplified a bit more.

The way that you deal with the 48mhz clock seems like it should fit in well
with the generic driver, just like all the rest (once the usb-st-common
stuff is moved into the ohci/ehci drivers), so the alternative would be
to make it all generic now.
