Add YAML devicetree binding for the MbedTEE Trusted Execution Environment driver.

The binding covers two platform configurations:

• ARM/AArch64 (TrustZone, SMC): two reserved-memory regions (rpc-t2r-ring and rpc-t2r-shm) plus a GIC SPI edge interrupt for TEE-to-REE notifications.
• RISC-V (IMSIC): three reserved-memory regions, adding rpc-r2t-ring for REE-to-TEE command submissions; no interrupts property (T2R notifications use IMSIC MSI allocated at runtime).

My bot found errors running 'make dt_binding_check' on your patch:

The base for the series is generally the latest rc1. A different dependency should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note that DT_SCHEMA_FILES can be set to your schema file to speed up checking your schema. However, it must be unset to test all examples with your schema.
