ARM: dts: imx6-sabreauto: add reset-gpios property for max7310_b
The reset pin to the port expander chip (MAX7310) is controlled by a gpio, so define a reset-gpios property to control it. There are three MAX7310's on the SabreAuto CPU card (max7310_[abc]), but all use the same pin for their reset. Since all can't acquire the same pin, assign it to max7310_b, that chip is needed by more functions (usb and adv7180).
