commit 6cda075aff67a1b9b5ba1b2818091dc939643b6c upstream.
sha224 AEAD test fails with:

[ 2.808743] talitos ff020000.crypto: MDEUISR 0x80100000_00000000

[ 2.884972] talitos ff020000.crypto: failed to reset channel 0
[ 2.890503] talitos ff020000.crypto: done overflow, internal time out, or rngu error: ISR 0x20000000_00020000
[ 2.900652] alg: aead: encryption failed on test 1 for authenc-hmac-sha224-cbc-3des-talitos: ret=22
This is due to SHA224 not being supported by the HW. Allthough for
hash we are able to init the hash context by SW, it is not
possible for AEAD. Therefore SHA224 AEAD has to be deactivated.
