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!
