crypto: ccp - Change data length declarations to u64
When performing a hash operation if the amount of data buffered and a request at or near the maximum data length is received then the length calcuation could wrap causing an error in executing the hash operation. Fix this by using a u64 type for the input and output data lengths in all CCP operations. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
