[PATCH 1/9] dt-bindings: nvmem: imx-ocotp: Add support for secure-enclave

[Frieder Schrempf]

From: Frieder Schrempf <frieder.schrempf@xxxxxxxxxx>

Some SoCs like the i.MX9 family allow full access to the fuses only
through the secure enclave firmware API. Add a property to reference
the secure enclave node and let the driver use the API.
