crypto: stm32 - Support for STM32 CRC32 crypto module
This module registers a CRC32 ("Ethernet") and a CRC32C (Castagnoli)
algorithm that make use of the STMicroelectronics STM32 crypto hardware.
Theses algorithms are compatible with the little-endian generic ones.
Both algorithms use ~0 as default seed (key).
With CRC32C the output is xored with ~0.
Using TCRYPT CRC32C speed test, this shows up to 900% speedup compared
to the crc32c-generic algorithm.
