[U-Boot] Sequoia EHCI

I created the file by myself. But it's nothing more than setting up register base addresses similar with ehci-ixp4xx.c ...

I checked out from current source a few days ago. Maybe it's not very straight forward to get ppc4xx  support working (as I originally thought). I'll take a look later this week.

thanks,

Chris

EHCI is currently not supported in U-Boot for PPC4xx.

I don't know of an ehci-ppc4xx.c file. Did you create it yourself?
