[U-Boot] PPC4xx: usbdev.c used at all?

Hi Marri,

I just "touched" the file "arch/powerpc/cpu/ppc4xx/usbdev.c" again to remove some GCC 4.6 compiler warnings. While doing this I wondered (again) if anybody is using this "driver" at all. I definitely never did. And I'm wondering if this code is useful at all.

So Marri (or anybody else): Do you need this driver in U-Boot?

If not, I'll just remove it in a short while.

Thanks.

Best regards, Stefan
