usb/isp1760: Allow to optionally trigger low-level chip reset via GPIOLIB.
Properly triggering the reset wire is necessary with the ISP1761 used on Terasic DE4 Altera-FPGA boards using a NIOS2 processor, for example. This is an optional implementation for the OF binding only. The other bindings just pass an invalid GPIO to the isp1760_register() routine. Example, usage in DTS: gpios = <&pio_isp1761rst_0 0 1>; to point to a GPIO controller from within the ISP1761 node: GPIO 0, active low.
