sunxi: provide default USB gadget setup

All the Allwinner boards use the same manufacturer, VID and PID for the
gadgets. Make them the defaults to remove some boilerplate from our
defconfigs.

 # USB Gadget support on a system involves
 #    (a) a peripheral controller, and
 #    (b) the gadget driver using it.
 #
 # NOTE:  Gadget support ** DOES NOT ** depend on host-side CONFIG_USB !!
 #
 #  - Host systems (like PCs) need CONFIG_USB (with "A" jacks).
 #  - Peripherals (like PDAs) need CONFIG_USB_GADGET (with "B" jacks).
 #  - Some systems have both kinds of controllers.
 #
 # With help from a special transceiver and a "Mini-AB" jack, systems with
 # both kinds of controller can also support "USB On-the-Go" (CONFIG_USB_OTG).

 	bool "USB Gadget Support"
 	help
 	   USB is a master/slave protocol, organized with one master
 	   host (such as a PC) controlling up to 127 peripheral devices.
 	   The USB hardware is asymmetric, which makes it easier to set up:
 	   you can't connect a "to-the-host" connector to a peripheral.
 	   U-Boot can run in the host, or in the peripheral.  In both cases
 	   you need a low level bus controller driver, and some software
 	   talking to it.  Peripheral controllers are often discrete silicon,
 	   or are integrated with the CPU in a microcontroller.  The more
 	   familiar host side controllers have names like "EHCI", "OHCI",
 	   or "UHCI", and are usually integrated into southbridges on PC
 	   motherboards.
 	   Enable this configuration option if you want to run U-Boot inside
 	   a USB peripheral device.  Configure one hardware driver for your
 	   peripheral/device side bus controller, and a "gadget driver" for
 	   your peripheral protocol.
