dt-bindings: clock: gpio-gate-clock: Convert to json-schema

Convert the simple GPIO clock gate Device Tree binding to json-schema
and fix-up references to this file in other text format bindings.
Jyri Sarha is the file's only editor/author so they have been added as
maintainer of the new yaml binding.

-Binding for simple gpio gated clock.
-
-This binding uses the common clock binding[1].
-
-[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Required properties:
-- compatible : shall be "gpio-gate-clock".
-- #clock-cells : from common clock binding; shall be set to 0.
-- enable-gpios : GPIO reference for enabling and disabling the clock.
-
-Optional properties:
-- clocks: Maximum of one parent clock is supported.
-
-Example:
-	clock {
-		compatible = "gpio-gate-clock";
-		clocks = <&parentclk>;
-		#clock-cells = <0>;
-		enable-gpios = <&gpio 1 GPIO_ACTIVE_HIGH>;
-	};
