rijndael-ppc: small speed-up for CBC and CFB encryption
* cipher/rijndael-ppc-common.h (AES_ENCRYPT_ALL): Remove * cipher/rijndael-ppc-functions.h (CFB_ENC_FUNC) (CBC_ENC_FUNC): Removed two block unrolled loop; Optimized single block loop for shorter critical-path.
Patch gives small ~3% performance increase for CBC and CFB
encryption, tested with POWER8.
