## Summary
Add stm32h7 support for CRC32 HW accelerator.
Extend stm32_crypto.c to add CRYPTO_CRC32 HW acceleration.
## Impact
- User experience: No adaptation required. This fix extends existing
behavior.
- Build: No impact.
- Hardware: Affects nucleo-h753zi board (and other stm32h7 based boards)
- Documentation: No impact.
- 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 (STM32H753ZI)
- Board: Nucleo-h753zi
- Configuration: nucleo-h753zi:crypto, then run "make menuconfig":
- Under System Type / STM32 Configuration / STM32 Peripheral Support:
- Enable CRC
- Under Application Configuration / Testing / drivers:
- Enable crc32 crypto test
Testing performed:
- Booted board and ran crc32 test utility; verify test used HW acceleration
Runtime testing:
From target console:
```
nsh> uname -a
NuttX 13.0.0 05832a4e62-dirty Jul 15 2026 15:58:20 arm nucleo-h753zi
