[PATCH 2/6] regulator: add bcm59056 pmu DT binding

[Matt Porter <mporter@linaro.org>]

Add a DT binding for the BCM59056 PMU. The binding inherits from
the generic regulator bindings.

+Required properties:
+- compatible: "brcm,bcm59056"
+- reg: I2C slave address
+- interrupts: interrupt for the PMU. Generic interrupt client node bindings
+  are described in interrupt-controller/interrupts.txt
+- regulators: This is the list of child nodes that specify the regulator
+  initialization data for defined regulators.  Generic regulator bindings
+  are described in regulator/regulator.txt.
+
+  The valid regulator-compatible values are:
+  	rfldo, camldo1, camldo2, simldo1, simlso2, sdldo, sdxldo,
+	mmcldo1, mmcldo2, audldo, micldo, usbldo, vibldo,
+	csr, iosr1, iosr2, msr, sdsr1, sdsr2, vsr
+
+Example:
+	pmu: bcm59056@8 {
+		compatible = "brcm,bcm59056";
+		reg = <0x08>;
+		interrupts = <GIC_SPI 215 IRQ_TYPE_LEVEL_HIGH>;
+		regulators {
+			#address-cells = <1>;
+			#size-cells = <0>;
+
+			rfldo_reg: regulator@0 {
+				reg = <0>;
+				regulator-compatible = "rfldo";
+				regulator-min-microvolt = <1200000>;
+				regulator-max-microvolt = <3300000>;
+				regulator-always-on;
+				regulator-boot-on;
