usb gadget: new "CDC Composite" gadget driver
This is a simple example of a composite gadget, combining two
Communications Class Device (CDC) functions: ECM and ACM.
This provides a clear example of how the composite gadget framework
is intended to work. It's surprising that MS-Windows (or at least,
XP and previous) won't "just work" with something this simple...

Not all USB peripheral controller hardware can support this driver.
All the highspeed-capable peripheral controllers with drivers now in
the mainline kernel seem to support this, as does omap_udc. But
many full speed controllers don't have enough endpoints, or (as with
the PXA controllers) don't support altsettings.
Lightly tested.
