ar71xx: Send power to USB port on WNR2200

This patch fixes ticket #15267 by enabling power on the
WNR2200's USB port. At present, the USB port on the WNR2200
is non-functional due to it not receiving power.

This patch defines an additional GPIO pin, but none of the
current GPIO definitions have been modified.
