			The OMAP GPIO driver hardcodes the MPIO chip base, but there is no point: we have already moved all consumers over to using descriptor look-ups. Drop the MPUIO GPIO base and use dynamic assignment. Root out the unused instances of the OMAP_MPUIO() macro and delete the unused OMAP_GPIO_IS_MPUIO() macro.
