target-ppc: Refactor AES Instructions
This patch refactors the PowerPC Advanced Encryption Standard (AES) instructions
to use the common AES tables (include/qemu/aes.h).
Specifically:
- vsbox is recoded to use the AES_sbox table.
- vcipher, vcipherlast and vncipherlast are all recoded to use the optimized
AES_t[ed][0-4] tables.
- vncipher is recoded to use a combination of InvS-Box, InvShiftRows and
InvMixColumns tables. It was not possible to use AES_Td[0-4] due to a
slight difference in how PowerPC implements vncipher.
