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.
