commit 70c4997f34b6c6888b3ac157adec49e01d0df2d5 upstream.
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)
