While the hardware consider them to be blockciphers, the
reference implementation defines them as streamciphers.
Do the right thing and set the blocksize to 1. This
was found by CONFIG_CRYPTO_MANAGER_EXTRA_TESTS.
This fixes the following issues:
skcipher: blocksize for ofb-aes-ppc4xx (16) doesn't match generic impl (1)
skcipher: blocksize for cfb-aes-ppc4xx (16) doesn't match generic impl (1)
