USB: at91_udc uses generic GPIO calls; minor cleanup

Various small at91_udc cleanups:

 - Use generic GPIO calls, not older platform-specific ones
 - Use gpio_request()/gpio_free()
 - Use VERBOSE_DEBUG convention, not older VERBOSE
 - Fix sparse complaint about parameter type (changed to gfp_t)
 - Add missing newline to some rarely-seen debug messages
 - Fix some old cleanup bugs on probe() fault paths

Also add a mechanism whereby rm9200 gpios can drive the D+ pullup
through an inverting transistor, based on a patch from Steve Birtles.
Most UDC drivers supporting a GPIO based pullup should probably have
such an option, but testing it requries such a board in hand!
