After commit e623c4303ed1 ("gpiolib: sanitize the return value of
gpio_chip::get_direction()"), a warning will be printed if the
gpio driver does not implement this callback.
Implement it for the sunxi driver. This is simply a matter of reading
out the mux value from the registers, then checking if it is one of
the GPIO functions and which direction it is.
