dt-bindings: gpio-mmio: Add compatible string for opencores,gpio

Browse source

In FPGA Development boards with GPIOs we use the opencores gpio verilog
rtl.  This is compatible with the gpio-mmio.  Add the compatible string
to allow as below.

Example:

        gpio0: gpio@91000000 {
                compatible = "opencores,gpio", "brcm,bcm6345-gpio";
                reg = <0x91000000 0x1>, <0x91000001 0x1>;
                reg-names = "dat", "dirout";
                gpio-controller;
                #gpio-cells = <2>;
                status = "okay";
        };
