The CONFIG_GPIO_MXC is necessary for all the i.MX SoCs, as it provides the basic
function of GPIO pin operations and IRQ operations, it is enabled by default previously
with " def_bool y " in Kconfig, now it is changed to tristate, so it should be explicitly
enabled in defconfig to make sure it does NOT break any existing functions, that is
why I list " i.MX GPIO is NOT default enabled now, so select CONFIG_GPIO_MXC as 
built-in manually " in commit msg, it aims to NOT change any previous behaviors.

thanks,
