[PATCH v3] dt-bindings: nvmem: mxs-ocotp: Document fsl,ocotp

[Fabio Estevam]

From: Fabio Estevam <festevam at denx.de>

Both imx23.dtsi and imx28.dtsi describe the OCOTP nodes in
the format:

compatible = "fsl,imx28-ocotp", "fsl,ocotp";

Document the "fsl,ocotp" entry to fix the following schema
warning:

efuse at 8002c000: compatible: ['fsl,imx23-ocotp', 'fsl,ocotp'] is too long
from schema $id: http://devicetree.org/schemas/nvmem/mxs-ocotp.yaml#

Fixes: 2c504460f502 ("dt-bindings: nvmem: Convert MXS OCOTP to json-schema")
