Subject: [PATCH] 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@...00000 {
-		compatible = "fujitsu,mb86s70-gpio";
-		reg = <0 0x31000000 0x10000>;
-		gpio-controller;
-		#gpio-cells = <2>;
-		clocks = <&clk 0 2 1>;
-	};
