Gerard Marull-Paretas fb60aab245 drivers: migrate includes to <zephyr/...> 
In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

Wealian Liao 5a9bc389f0 driver: gpio: nct38xx: Add NCT38XX gpio driver support 
NCT38XX series, which are i2c-based chips, support a different number
of GPIO functionality. For NCT3807, it has 2 GPIO ports on the same i2c
device address. For NCT3808, it has 2 GPIO ports on different i2c
device addresses. This commit adds NCT38XX GPIO driver support &
provides the interrupt handler for the share alert pin.

The following is NCT3807 devicetree node example:
```
&i2c0_0 {
	nct3807_0: nct3807@70 {
		#address-cells = <1>;
		#size-cells = <0>;
		compatible = "nuvoton,nct38xx-gpio";
		reg = <0x70>;
		label = "NCT3807_0";

		gpio@0 {
			compatible = "nuvoton,nct38xx-gpio-port";
			reg = <0x0>;
			label = "NCT3807_0_GPIO0";
			gpio-controller;
			#gpio-cells = <2>;
			ngpios = <8>;
			pin_mask = <0xff>;
			pinmux_mask = <0xf7>;
		};

		gpio@1 {
			compatible = "nuvoton,nct38xx-gpio-port";
			reg = <0x1>;
			label = "NCT3807_0_GPIO1";
			gpio-controller;
			#gpio-cells = <2>;
			ngpios = <8>;
			pin_mask = <0xff>;
		};
	};
};
```
