**Arguments:**

- Takes target processor as the first argument.
- Possible second positional arguments are: 1) linux_dt 2) zephyr_dt
- Possible second positional arguments are: ``linux_dt`` for Linux domain DTS (see Zephyr documentation for ``zephyr_domain_dts`` assist).
- In absence of second positional argument, create the processor specific domain device tree for baremetal
