Add a device tree binding for the TEE-based remote processor control service implemented as an OP-TEE Trusted Application identified by UUID 80a4c275-0a47-4905-8285-1486a9771a08.
The TEE service node is a child of the "linaro,optee-tz" firmware node and acts as a container for remoteproc devices that are controlled via TEE.
In addition, the "linaro,optee-tz" binding is updated to specify the '#address-cells' and '#size-cells' values used for child TEE service nodes.
