dt-bindings: gpio: rcar: Convert to json-schema

Convert the Renesas General-Purpose Input/Output Ports (GPIO) Device
Tree binding documentation to json-schema.

Drop the deprecated "renesas,gpio-rcar" compatible value.
Document missing properties.
Drop the first example, as it doesn't add much value.

-
-    When compatible with the generic version nodes must list the
-    SoC-specific version corresponding to the platform first followed by
-    the generic version.
-
-  - reg: Base address and length of each memory resource used by the GPIO
-    controller hardware module.
-
-  - interrupts: Interrupt specifier for the controllers interrupt.
-
-  - gpio-controller: Marks the device node as a gpio controller.
-  - #gpio-cells: Should be 2. The first cell is the GPIO number and the second
-    cell specifies GPIO flags, as defined in <dt-bindings/gpio/gpio.h>. Only the
-    GPIO_ACTIVE_HIGH and GPIO_ACTIVE_LOW flags are supported.
-  - gpio-ranges: See gpio.txt.
-
-Optional properties:
-
-  - clocks: Must contain a reference to the functional clock.  The property is
-    mandatory if the hardware implements a controllable functional clock for
-    the GPIO instance.
-
-  - gpio-reserved-ranges: See gpio.txt.
-
-Please refer to gpio.txt in this directory for the common GPIO bindings used by
-client devices.
-
-The GPIO controller also acts as an interrupt controller. It uses the default
-two cells specifier as described in Documentation/devicetree/bindings/
-interrupt-controller/interrupts.txt.
