pinctrl-sunxi: sunxi_pinctrl_gpio_direction_in/output: use correct offset

The commit that sets the direction directly without calling
pinctrl_gpio_direction(), forgot to add chip->base to the offset when
calling sunxi_pmx_gpio_set_direction().

This caused failures for various Allwinner boards which have two
GPIO blocks.
