[bsp][k230]:add gnne driver

Requirement: The BSP for the k230 platform in the RT-Thread repository does not yet have a gnne driver.
Solution: Provide gnne driver for the k230 platform in the RT-Thread repository.
- Implements mutex lock mechanism for AI2D and GNNE modules.
- Adds HARDLOCK_AI2D support in hardlock driver for mutual exclusion.
- Implements poll operation for device status monitoring.
- Updates documentation in bsp/README.md.
