ACE H/W acceleration support is added to hash
which can be used to test SHA 256 hash algorithm.
Tested with command "hash sha256 0x40008000 0x2B 0x40009000".
Used mm and md to write a standard string to memory location
0x40008000 and ran the above command to verify the output.

Changes sice v2:
- Added new nodes for SHA1 and SHA256 in struct hash_algo for the case
when ACE is enabled.
- Added new declaration for function pointer hash_func_ws with
different return type.
