gpio: lp87565: Set proper output level and direction for direction_output
The value argument of lp87565_gpio_direction_output() means output level rather than gpio direction. Signed-off-by: Axel Lin <axel.lin@ingics.com> Reviewed-by: Keerthy <j-keerthy@ti.com> Tested-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
