dt-bindings: pinctrl: Update pinctrl-ingenic for JZ4725B and GPIO merge

Browse Source 
The pinctrl-ingenic driver now supports the JZ4725B SoC.

Furthermore, the gpio-ingenic driver was dropped and the pinctrl-ingenic
driver is now responsible for providing the GPIO functionality.

Ingenic jz47xx GPIO controller
That the Ingenic GPIO driver node must be a sub-node of the Ingenic pinctrl
driver node.
Required properties:
--------------------
- compatible: Must contain one of:
- "ingenic,jz4740-gpio"
- "ingenic,jz4770-gpio"
- "ingenic,jz4780-gpio"
- reg: The GPIO bank number.
- interrupt-controller: Marks the device node as an interrupt controller.
- interrupts: Interrupt specifier for the controllers interrupt.
- #interrupt-cells: Should be 2. Refer to
../interrupt-controller/interrupts.txt for more details.
- 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: Range of pins managed by the GPIO controller. Refer to
'gpio.txt' in this directory for more details.
Example:
--------
&pinctrl {
#address-cells = <1>;
#size-cells = <0>;
gpa: gpio@0 {
compatible = "ingenic,jz4740-gpio";
reg = <0>;
gpio-controller;
gpio-ranges = <&pinctrl 0 0 32>;
#gpio-cells = <2>;
interrupt-controller;
#interrupt-cells = <2>;
interrupt-parent = <&intc>;
interrupts = <28>;
};
};

The pinctrl node can have optional sub-nodes for the Ingenic GPIO driver;
