sparc64: Move AES driver over to a methods based implementation.
Instead of testing and branching off of the key size on every encrypt/decrypt call, use method ops assigned at key set time. Reverse the order of float registers used for decryption to make future changes easier. Align all assembler routines on a 32-byte boundary. Signed-off-by: David S. Miller <davem@davemloft.net>
