From: Christophe Leroy <christophe.leroy@xxxxxx>
commit b8fbdc2bc4e71b62646031d5df5f08aafe15d5ad upstream.
SEC1 doesn't support SHA384/512, so it doesn't require
longer keys.
This patch reduces the max key size when the driver
is built for SEC1 only.
Signed-off-by: Christophe Leroy <christophe.leroy@xxxxxx>
Fixes: 03d2c5114c95 ("crypto: talitos - Extend max key length for SHA384/512-HMAC and AEAD")
