CR ENGR00030367: Fix invalid gpio mode for cspi on imx31ads
Description: This patch fixes invalid GPIO mode settings for CSPI pins on
i.MX31ADS. Since the CSPI pins on i.MX31ADS doesnot support GPIO mode, the
gpio_spi_inactive() function does nothing. As a result, the CSPI pins retain
its primary functional mode even after they are set to inactivate.
