[PATCH 1/6] Remove variable size restrictions in i.MX23's gpio managing routines

[Juergen Beisert <jbe@pengutronix.de>]

There is no really need for restricted variable types for the parameters.
Replace them by standard C types with the same behaviour. Only imx_gpio_mode()
need it, to ensure GPIO's bit settings.
