ARM: tegra: tps6586x: add empty function direction_input

-on reset default direction is in NOT_CONFIGURED (neither input
    nor output) mode.
-as tps6586x driver has not implemented direction_input, gpiolib
    sysfs only creates a value node not any direction node for
    each gpios. so from user space there is no way to set direction
    (or to call function tps6586x_update).
-by adding empty function for direction_input solves the above
    problem by providing direction node in sysfs.
