crypto: omap-sham - Add SHA384 and SHA512 Support
Adding support for SHA348 and SHA512 in addition to MD5, SHA1, SHA224 SHA256 that the omap sha module supports. In order to add the support - Removed hard coded register offsets and passing offsets from pdata - Updating Flag offsets so that they can be used for SHA256 and SHA512 - Adding the algo info.
