Some aead algorithms set .cra_flags = CRYPTO_ALG_TYPE_AEAD. But this is
redundant with the C structure type ('struct aead_alg'), and
crypto_register_aead() already sets the type flag automatically,
clearing any type flag that was already there. Apparently the useless
assignment has just been copy+pasted around.
So, remove the useless assignment from all the aead algorithms.
This patch shouldn't change any actual behavior.

In the AES cases enum spu_cipher_type and enum hash_type have
the same values, so the assignment is fine. Explicitly cast
the enum type conversion.
This fixes two warnings when building with clang:
drivers/crypto/bcm/cipher.c:821:34: warning: implicit conversion from
enumeration type 'enum spu_cipher_type' to different enumeration
type 'enum hash_type' [-Wenum-conversion]
hash_parms.type = cipher_parms.type;
~ ~~~~~~~~~~~~~^~~~
drivers/crypto/bcm/cipher.c:1412:26: warning: implicit conversion from
enumeration type 'enum spu_cipher_type' to different enumeration
type 'enum hash_type' [-Wenum-conversion]
hash_parms.type = ctx->cipher_type;

The usage of of_device_get_match_data reduce the code size a bit.
Furthermore, it prevents an improbable dereference when

Add support to explicity ACK mailbox message
because after sending message we can know
the send status via error attribute of brcm_message.
This is needed to support "txdone_ack" supported in
mailbox controller driver.

Enhance code to generically support cases where DMA rings

New hardware has underlying DMA engine-FlexRM with 32 rings
which can be used to communicate to any of the available
