Nathan Chancellor 18e732b803 crypto: ccree - avoid implicit enum conversion
Clang warns when one enumerated type is implicitly converted to another
and this happens in several locations in this driver, ultimately related
to the set_cipher_{mode,config0} functions. set_cipher_mode expects a mode
of type drv_cipher_mode and set_cipher_config0 expects a mode of type
drv_crypto_direction.

drivers/crypto/ccree/cc_ivgen.c:58:35: warning: implicit conversion from
enumeration type 'enum cc_desc_direction' to different enumeration type
'enum drv_crypto_direction' [-Wenum-conversion]
        set_cipher_config0(&iv_seq[idx], DESC_DIRECTION_ENCRYPT_ENCRYPT);

drivers/crypto/ccree/cc_hash.c:99:28: warning: implicit conversion from
enumeration type 'enum cc_hash_conf_pad' to different enumeration type
'enum drv_crypto_direction' [-Wenum-conversion]
                set_cipher_config0(desc, HASH_DIGEST_RESULT_LITTLE_ENDIAN);

drivers/crypto/ccree/cc_aead.c:1643:30: warning: implicit conversion
from enumeration type 'enum drv_hash_hw_mode' to different enumeration
type 'enum drv_cipher_mode' [-Wenum-conversion]
        set_cipher_mode(&desc[idx], DRV_HASH_HW_GHASH);

Since this fundamentally isn't a problem because these values just
represent simple integers for a shift operation, make it clear to Clang
that this is okay by making the mode parameter in both functions an int.
