Add nucleo-h7s3l8 board support
## Summary
Add support for STM32H7S8-DK board including Ethernet.
## Impact
- User experience: No adaptation required. This fix extends existing
behavior.
- Build: No impact.
- Hardware: Affects stm32h7s8-dk board.
- Documentation: Add stm32h7s8-dk platform
- Security: No impact.
- Compatibility: Backward compatible - adds functionality
## Testing
Build Host:
- OS: Ubuntu 24.04.4 LTS
- Compiler: arm-none-eabi-gcc 13.2.1
Target:
- Architecture: ARM (STM32H7S3L8)
- Board: STM32H7S8-DK
- Configuration: Default stm32h7s8:boot-xip and stm32h7s8-dk:jumbo-xip
configurations(to create external flash and bootloader images)
Testing performed:
- Connected Ethernet to stm32h7s8-dk
- Burnt/booted built images
- Ran ostest to successful completion
- Ran commands/log as shown in target documentation
Runtime testing:
From target console:
