Dear Stephen Warren,

> Commit 8f62ca6 "usb: ehci: Support interrupt transfers via periodic list"
> didn't include any cache management in the new interrupt transfer path.
> It also added an extra write to or_asynclistaddr in usb_lowlevel_init(),
> without having flushed out the data there.
>
> Add the missing cache management calls, so that the code works again.
