[Akshay Saraswat]

This patch set adds hardware acceleration for SHA 256
with the help of ACE.

		- Added falling back to software sha256 in case length exceeds buffer limit.
		- Reduced one tab at lines 533, 559 and 571 in the patch.

		- Removed blank line at line 561 in the patch.

        - Patch-2: 
		- Added "SHA1" in the comment for config.
        - Patch-3: 
		- 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.
        - Patch-4: 
		- New patch to enable config for hash command.
