The current implementation of the CRC32 perhipheral does not enable the CRC32 clock.
On the STM32F446, this causes all calculations against this peripheral to emit an incorrect null instead of the checksum.
This PR enables the CRC clock when the HAL's peripheral is acquired, and disables it when released.
