Laxman Dewangan 5763318f56 gpio: palmas: add dt support
Add of_device_id table for Palma GPIO to be enable the
driver from DT file.

The driver can be registered from DT file as:
	palmas: tps65913@58 {
		:::::::::::
		palmas_gpio: palmas_gpio {
			compatible = "ti,palmas-gpio";
			gpio-controller;
			#gpio-cells = <2>;
		};
	};

Palmas GPIO controller bindings
Required properties:
- compatible:
- "ti,palams-gpio" for palma series of the GPIO controller
- "ti,tps80036-gpio" for Palma series device TPS80036.
- "ti,tps65913-gpio" for palma series device TPS65913.
- "ti,tps65914-gpio" for palma series device TPS65914.
- #gpio-cells : Should be two.
- first cell is the gpio pin number
- second cell is used to specify the gpio polarity:
0 = active high
1 = active low
- gpio-controller : Marks the device node as a GPIO controller.
Note: This gpio node will be sub node of palmas node.
Example:
palmas: tps65913@58 {
:::::::::::
palmas_gpio: palmas_gpio {
compatible = "ti,palmas-gpio";
gpio-controller;
#gpio-cells = <2>;
};
:::::::::::
};
