regulator: 88pg86x: add DT bindings document

The only device-specific node names are "buck1" and "buck2" for the two
regulators present on the device. Sleep mode GPIO and per-regulator GPIO
enable pins are not exposed (the driver does not support them either).

Marvell 88PG867/88PG868 voltage regulators
Required properties:
- compatible: one of "marvell,88pg867", "marvell,88pg868";
- reg: I2C slave address.
Optional subnodes for regulators: "buck1", "buck2", using common regulator
bindings given in <Documentation/devicetree/bindings/regulator/regulator.txt>.
Example:
pg868@19 {
compatible = "marvell,88pg868";
reg = <0x19>;
vcpu: buck1 {
regulator-boot-on;
regulator-always-on;
regulator-min-microvolt = <1000000>;
regulator-max-microvolt = <1350000>;
};
};
