Subject: [PATCH] dt-bindings: nvmem: brcm,ocotp: convert to dtschema

Convert the Broadcom OTP memory controller to newer DT schema.
Created DT schema based on the .txt file which had
`compatible`, `reg` `brcm,ocotp-size` as the
required properties.

-Broadcom OTP memory controller
-
-Required Properties:
-- compatible: "brcm,ocotp" for the first generation Broadcom OTPC which is used
-  in Cygnus and supports 32 bit read/write. Use "brcm,ocotp-v2" for the second
-  generation Broadcom OTPC which is used in SoC's such as Stingray and supports
-  64-bit read/write.
-- reg: Base address of the OTP controller.
-- brcm,ocotp-size: Amount of memory available, in 32 bit words
-
-Example:
-
-otp: otp@...c800 {
-	compatible = "brcm,ocotp";
-	reg = <0x0301c800 0x2c>;
-	brcm,ocotp-size = <2048>;
-};
