crypto: caam - fix DKP detection logic
The detection for DKP (Derived Key Protocol) relied on the value
of the setkey function. This was broken by the recent change which
added des3_aead_setkey.
This patch fixes this by introducing a new flag for DKP and setting
that where needed.
Fixes: 1b52c40919e6 ("crypto: caam - Forbid 2-key 3DES in FIPS mode")
