dt-bindings: gpio: Convert UniPhier GPIO to json-schema

Convert the UniPhier GPIO controller binding to DT schema format.

I omitted the 'gpio-ranges' property because it is defined in the
dt-schema project (/schemas/gpio/gpio.yaml).

As of writing, the 'gpio-ranges-group-names' is not defined in that
file despite it is a common property described in
Documentation/devicetree/bindings/gpio/gpio.txt
So, I defined it in this schema.

-UniPhier GPIO controller
-
-Required properties:
-- compatible: Should be "socionext,uniphier-gpio".
-- reg: Specifies offset and length of the register set for the device.
-- 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.
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells: Should be 2.  The first cell defines the interrupt number.
-  The second cell bits[3:0] is used to specify trigger type as follows:
-    1 = low-to-high edge triggered
-    2 = high-to-low edge triggered
-    4 = active high level-sensitive
-    8 = active low level-sensitive
-  Valid combinations are 1, 2, 3, 4, 8.
-- ngpios: Specifies the number of GPIO lines.
-- gpio-ranges: Mapping to pin controller pins (as described in gpio.txt)
-- socionext,interrupt-ranges: Specifies an interrupt number mapping between
-  this GPIO controller and its interrupt parent, in the form of arbitrary
-  number of <child-interrupt-base parent-interrupt-base length> triplets.
-
-Optional properties:
-- gpio-ranges-group-names: Used for named gpio ranges (as described in gpio.txt)
-
-Example:
-	gpio: gpio@55000000 {
-		compatible = "socionext,uniphier-gpio";
-		reg = <0x55000000 0x200>;
-		interrupt-parent = <&aidet>;
-		interrupt-controller;
-		#interrupt-cells = <2>;
-		gpio-controller;
-		#gpio-cells = <2>;
-		gpio-ranges = <&pinctrl 0 0 0>;
-		gpio-ranges-group-names = "gpio_range";
-		ngpios = <248>;
-		socionext,interrupt-ranges = <0 48 16>, <16 154 5>, <21 217 3>;
-	};
-
-Consumer Example:
-
-	sdhci0_pwrseq {
-		compatible = "mmc-pwrseq-emmc";
-		reset-gpios = <&gpio UNIPHIER_GPIO_PORT(29, 4) GPIO_ACTIVE_LOW>;
-	};
-
-Please note UNIPHIER_GPIO_PORT(29, 4) represents PORT294 in the SoC document.
-Unfortunately, only the one's place is octal in the port numbering.  (That is,
-PORT 8, 9, 18, 19, 28, 29, ... are missing.)  UNIPHIER_GPIO_PORT() is a helper
-macro to calculate 29 * 8 + 4.
