dt-bindings: gpio: Convert Fujitsu MB86S7x GPIO to DT schema 



Convert the Fujitsu MB86S7x GPIO binding to DT schema format.

The "socionext,synquacer-gpio" compatible was not documented, but is
compatible with "fujitsu,mb86s70-gpio" and is in use (in u-boot
Synquacer dts).

Fujitsu MB86S7x GPIO Controller

-------------------------------



Required properties:

- compatible: Should be "fujitsu,mb86s70-gpio"

- reg: Base address and length of register space

- clocks: Specify the clock

- gpio-controller: Marks the device node as a gpio controller.

- #gpio-cells: Should be <2>. The first cell is the pin number and the

  second cell is used to specify optional parameters:

   - bit 0 specifies polarity (0 for normal, 1 for inverted).



Examples:

	gpio0: gpio@31000000 {

		compatible = "fujitsu,mb86s70-gpio";

		reg = <0 0x31000000 0x10000>;

		gpio-controller;

		#gpio-cells = <2>;

		clocks = <&clk 0 2 1>;

	};
