[U-Boot] [PATCH] usb: ehci: add missing cache managment

[Marek Vasut]

Dear Stephen Warren,

> From: Stephen Warren <swarren at nvidia.com>
> 
> 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.
> 
> This allows the USB keyboard on Tegra's Seaboard/Springbank boards to
> work.
