staging: mt7621-gpio: use GPIOF_DIR_OUT and GPIOF_DIR_IN macros instead of custom values
There are macros in gpio kernel's headers to define direction of a gpio. Use them instead of return custom '0' and '1' values. Signed-off-by: Sergio Paracuellos <sergio.paracuellos@gmail.com> Reviewed-by: NeilBrown <neil@brown.name> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
