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 v6:
* Added more formating for properties.
Changes in v4:
* Added the GPIO properties.
Changes in v3:
* Changed the example node lable to pmic from lp8733.

+TI LP873X PMIC 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>;
+
