Add a DT binding for the BCM590xx PMUs. The binding inherits from
the generic regulator bindings.

What do these reg values mean, they don't seem to be documented in the
binding?

Dropped this and the deprecated regulator-compatible property in v3 in
favor of using node name matching.

+-------------------------------
+
+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

+Required properties:

+Optional properties:
+- 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 for BCM59056 are:
+  	rfldo, camldo1, camldo2, simldo1, simlso2, sdldo, sdxldo,
+	mmcldo1, mmcldo2, audldo, micldo, usbldo, vibldo,

+Example:
+	pmu: bcm59056@8 {

+		reg = <0x08>;
+		interrupts = <GIC_SPI 215 IRQ_TYPE_LEVEL_HIGH>;
