[PATCH v4 1/3] Documentation: mfd: LP873X: Add information for the mfd driver

[Keerthy]

The lp873x series of PMICs have a bunch of regulators and a couple
of GPO(General Purpose Outputs).
Add information for the mfd and regulator drivers.

Changes in v4:

  * Added the GPO properties.

Changes in v3:

+TI LP873X MFD driver
+
+Required properties:
+  - compatible:		"ti,lp8732", "ti,lp8733"
+  - reg:		I2C slave address.
+  - gpio-controller :	Marks the device node as a GPIO Controller.
+  - #gpio-cells	:	Should be two.  The first cell is the pin number and
+			the second cell is used to specify flags.
+			See ../gpio/gpio.txt for more information.
+  - regulators: :	List of child nodes that specify the regulator
+			initialization data.
+Example:
+
+pmic: lp8733@60 {
+	compatible = "ti,lp8733";
+	reg = <0x60>;
+	gpio-controller;
+	#gpio-cells = <2>;
