Convert the ti,secure-proxy to yaml for better checks and documentation. Differences being mostly in the examples: - Dropped the example usage of mailbox client, it is better done in tisci node definition. - Switched reg usage for address-cells and size-cells 1 - aligned with schema checks as well. - included header in example for a buildable example. While at this, lets make sure to support upto 100 rx threads even though typically upto 1 threads is practically in use. NOTE: The following checkpatch warning is generated since we do include the header in the example, but this is a false positive warning. WARNING: DT binding docs and includes should be a separate patch.

The Texas Instruments' secure proxy is a mailbox controller that has
|
|
configurable queues selectable at SoC(System on Chip) integration. The
|
|
Message manager is broken up into different address regions that are
|
|
called "threads" or "proxies" - each instance is unidirectional and is
|
|
instantiated at SoC integration level by system controller to indicate
|
|
receive or transmit path.
