CRC32C: Add soft module dependency to load other accelerated crc32c modules

We added the soft module dependency of crc32c module alias
to generic crc32c module so other hardware accelerated crc32c
modules could get loaded and used before the generic version.
We also renamed the crypto/crc32c.c containing the generic
crc32c crypto computation to crypto/crc32c_generic.c according
to convention.
