Convert linaro,optee-tz to json schema format for better documentation
and error checks.

NOTE:
1. This change does introduce a stricter naming convention for
   optee nodes.
2. We do have false positive checkpatch warning with this patch:
   "DT binding docs and includes should be a separate patch"

-OP-TEE is a piece of software using hardware features to provide a Trusted
-Execution Environment. The security can be provided with ARM TrustZone, but
-also by virtualization or a separate chip.
-
-We're using "linaro" as the first part of the compatible property for
-the reference implementation maintained by Linaro.
-
-* OP-TEE based on ARM TrustZone required properties:
-
-- compatible     : should contain "linaro,optee-tz"
-
-- method         : The method of calling the OP-TEE Trusted OS. Permitted
-                   values are:
-
-                   "smc" : SMC #0, with the register assignments specified
-                          in drivers/tee/optee/optee_smc.h
-
-                   "hvc" : HVC #0, with the register assignments specified
-                          in drivers/tee/optee/optee_smc.h

-Example:
-       firmware {
-               optee {
-                       compatible = "linaro,optee-tz";
-                       method = "smc";

Are these links supposed to work?

Could possibly some day, but no. Just convention for json-schema.
