crypto: crc32 - Add ARM64 CRC32 hw accelerated module
This module registers a crc32 algorithm and a crc32c algorithm
that use the optional CRC32 and CRC32C instructions in ARMv8.
Tested on AMD Seattle.
Improvement compared to crc32c-generic algorithm:
TCRYPT CRC32C speed test shows ~450% speedup.
Simple dd write tests to btrfs filesystem show ~30% speedup.
