ARM: s3c24xx: Switch to common GPIO controlled UDC pullup implementation
Currently all boards using the s3c2410_udc driver use a GPIO to control the state of the pullup, as a result the same code is reimplemented in each board This patch changes these boards to use the common implementation for GPIO controlled pullup in the UDC driver.
