arm/mx2: define seperate gpio port descriptions for imx21 and imx27
As the gpio ports have different addresses on imx21 and imx27 there are two different port descriptions needed if not relying on the overloaded cpp macro IO_ADDRESS. So some cpp magic is added to minimize code duplication. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
