mpc85xx: remove USB support from kernel

This removes USB support from the compiled kernel. Because of this, the
kernel is just small enough for the TP-Link WDR4900 to boot the
resulting kernel.

This is necessary to support the WDR4900 in the upcoming 19.xx release.
In the long run, this should be fixed with a second stage bootloader, as
the vendor bootloader only loads the first 2684k bytes.
