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
of_match_device() return NULL.

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
are greater than or equal to number of SPU engines.
New hardware has underlying DMA engine-FlexRM with 32 rings
which can be used to communicate to any of the available
10 SPU engines.

Check return value from call to of_match_device()
in order to prevent a NULL pointer dereference.
In case of NULL print error message and return -ENODEV
