crypto: stm32/crc32 - protect from concurrent accesses
Protect STM32 CRC device from concurrent accesses.
As we create a spinlocked section that increase with buffer size,
we provide a module parameter to release the pressure by splitting
critical section in chunks.
Size of each chunk is defined in burst_size module parameter.
By default burst_size=0, i.e. don't split incoming buffer.
