dt-bindings: mfd: Convert lp873x.txt to json-schema

Browse Source 
Convert the lp873x binding to DT schema format. The gpio-controller
and #gpio-cells properties were removed from required because using
the device as a GPIO controller is optional.

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.
- xxx-in-supply: Phandle to parent supply node of each regulator
populated under regulators node. xxx can be
buck0, buck1, ldo0 or ldo1.
- 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>;
buck0-in-supply = <&vsys_3v3>;
buck1-in-supply = <&vsys_3v3>;
ldo0-in-supply = <&vsys_3v3>;
ldo1-in-supply = <&vsys_3v3>;
