s390/crc32-vx: add crypto API module for optimized CRC-32 algorithms
Add a crypto API module to access the vector extension based CRC-32 implementations. Users can request the optimized implementation through the shash crypto API interface. Signed-off-by: Hendrik Brueckner <brueckner@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
