Add the device tree bindings and device-tree node definitions for this HSM M4F core. The HSM M4 core is typically booted early from the bootloader and the driver for the same is posted in U-Boot mailing list[0]. v2: Changelog: [Krzysztof Kozlowski]: In [PATCH v2 1/3] 1. Update commit msg to remove redundant "bindings". 2. Update filename to match compatible. 3. Remove "address-cells" & "size-cells" property. These belong to the device's parent node. 4. Drop description from firmware-name property. 5. Fix indentation for DT example.
