dt-bindings: crypto: Convert brcm,spum-crypto to DT schema

Convert the Broadcom SPUM/SPU2 binding to DT schema format. It's a
straight forward conversion.

-The Broadcom Secure Processing Unit (SPU) hardware supports symmetric
-cryptographic offload for Broadcom SoCs. A SoC may have multiple SPU hardware
-blocks.
-
-Required properties:
-- compatible: Should be one of the following:
-  brcm,spum-crypto - for devices with SPU-M hardware
-  brcm,spu2-crypto - for devices with SPU2 hardware
-  brcm,spu2-v2-crypto - for devices with enhanced SPU2 hardware features like SHA3
-  and Rabin Fingerprint support
-  brcm,spum-nsp-crypto - for the Northstar Plus variant of the SPU-M hardware
-
-- reg: Should contain SPU registers location and length.
-- mboxes: The mailbox channel to be used to communicate with the SPU.
-  Mailbox channels correspond to DMA rings on the device.
-
-Example:
-	crypto@612d0000 {
-		compatible = "brcm,spum-crypto";
-		reg = <0 0x612d0000 0 0x900>;
-		mboxes = <&pdc0 0>;
-	};
