u-boot: Enable USB with a preboot command 

We need to initialize the USB subsystem before we can use USB devices
like keyboards and external disks, by running `usb start`. Use the
PREBOOT config option to run the necessary command before U-Boot tries
to automatically boot anything. It's already enabled for boards other
than gru_kevin and gru_bob, so just update those two configs.
