Hook, Gary b55ca259c2 crypto: ccp - fix AES CFB error exposed by new test vectors

[ Upstream commit c3b359d656 ]

Updated testmgr will exhibit this error message when loading the
ccp-crypto module:

alg: skcipher: cfb-aes-ccp encryption failed with err -22 on test vector 3, cfg="in-place"

Update the CCP crypto driver to correctly treat CFB as a streaming mode
cipher (instead of block mode). Update the configuration for CFB to
specify the block size as a single byte;

Fixes: 2b789435d7 ('crypto: ccp - CCP AES crypto API support')
