[ARM] 2950/1: i.MX gpio setup function
Patch from Sascha Hauer Current implementation of imx_gpio_mode does not allow to configure all alternate routing possibilities of the i.MX. With this patch every bit in the gpio setup registers has a corresponding bit in the gpio_mode parameter, so every routing should be possible now.
