[PADLOCK] Move fast path work into aes_set_key and upper layer
Most of the work done aes_padlock can be done in aes_set_key. This
means that we only have to do it once when the key changes rather
than every time we perform an encryption or decryption.
This patch also sets cra_alignmask to let the upper layer ensure
that the buffers fed to us are aligned correctly.
