Need to load ehci 2.0 USB driver/module before USB 1.1 modules

I have an XO-1 with os11 which complained in dmesg:

Warning! ehci_hcd should always be loaded before uhci_hcd and ohci_hcd, not after"

And although it looked like their dmesg entries were mixed, OHCI likely was loaded before EHCI was.

Unless there is an OLPC-specific reason otherwise we likely should heed this advice.

On an XO-1.5 with os12 it looked like we loaded these in the correct order.
