crypto/aes: rewrite ppc64le block crypting
This unrolls the counter loop and simplifies the load/storing
of text/ciphertext and keys by using unaligned VSX memory
operations.
Performance delta on POWER9:
name old time/op new time/op delta
Encrypt 19.9ns ± 0% 14.9ns ± 0% -24.95%
Decrypt 19.8ns ± 0% 14.6ns ± 0% -26.12%
