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!
