The AT91 family of SoCs have a USB device controller, this patch should enable
the feature
and cleanup the default config of the at91 target to play nicely with the
gadget modules.
kmod-usb-eth-gadget is added as a default module to retain the same board
functionality as
before this patch, though, the 'debug' network interface in the default config
is rather
useless.
