gpio: mxs: implement get_direction callback gpiolib's gpiod_get_direction() function returns the EINVAL error if .get_direction callback is not defined. The patch implements the callback for mxs chip which is useful for debugging. Inspired by arch/arm/mach-at91/gpio.c On the moment the patch is required to get the patch "serial: mxs-auart: enable PPS support" working. It is planned to introduce new mctrl_gpio helpers to avoid gpiod_get_direction() function.
