crypto: ccp - Add hash state import and export support

Browse source

Commit 8996eafdcb ("crypto: ahash - ensure statesize is non-zero")
added a check to prevent ahash algorithms from successfully registering
if the import and export functions were not implemented. This prevents
an oops in the hash_accept function of algif_hash. This commit causes
the ccp-crypto module SHA support and AES CMAC support from successfully
registering and causing the ccp-crypto module load to fail because the
ahash import and export functions are not implemented.

Update the CCP Crypto API support to provide import and export support
for ahash algorithms.
