Convert the Broadcom iProc PDC mailbox binding to DT schema format. It's a straightforward conversion.

-The PDC driver manages data transfer to and from various offload engines
-on some Broadcom SoCs. An SoC may have multiple PDC hardware blocks. There is
-one device tree entry per block.  On some chips, the PDC functionality is
-handled by the FA2 (Northstar Plus).
-
-Required properties:
-- compatible : Should be "brcm,iproc-pdc-mbox" or "brcm,iproc-fa2-mbox" for
-  FA2/Northstar Plus.
-- reg: Should contain PDC registers location and length.
-- interrupts: Should contain the IRQ line for the PDC.
-- #mbox-cells: 1
-- brcm,rx-status-len: Length of metadata preceding received frames, in bytes.
-
-Optional properties:
-- brcm,use-bcm-hdr:  present if a BCM header precedes each frame.
-
-Example:
-	pdc0: iproc-pdc0@612c0000 {
-		compatible = "brcm,iproc-pdc-mbox";
-		reg = <0 0x612c0000 0 0x445>;  /* PDC FS0 regs */
-		interrupts = <GIC_SPI 187 IRQ_TYPE_LEVEL_HIGH>;
-		#mbox-cells = <1>;   /* one cell per mailbox channel */
-		brcm,rx-status-len = <32>;
-		brcm,use-bcm-hdr;
-	};
