arm: mps3_an547: Add SoC support for the AN547 on MPS3
The AN547 is a Soft Macro Model implementation of the SSE-300 subsystem with Ethos-U55 and Cortex-M55 components targeting the MPS3 board. The SoC support is based on the AN521 MPS2+ support that already exists in Zephyr. Signed-off-by: Kumar Gala <kumar.gala@linaro.org>
