[U-Boot] [PATCH 4/5 v4] gen: Add ACE acceleration to hash

[Akshay Saraswat]

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 since v1:
	- Added sha256 support to "hash" command instead of new sha256 command.

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.

Changes sice v3:
	- Changed command names to lower case in algo struct.
	- Added generic ace_sha config.
