[PATCH] pinctrl/amd: add get_direction handler

On boot, gpiochip_add_data() initializes the FLAG_IS_OUT bit in desc->flags iff its gpio_chip does not have ->direction_input() handler, else it is initialized to 0, which implies the GPIO is an "input". Later, the sysfs "direction" handler will use gpiod_get_direction() to get the current
