Add int return values to SHA-512 function calls

Browse source 
The following function calls are being deprecated to introduce int
return values.
    * mbedtls_sha512()
    * mbedtls_sha512_starts()
    * mbedtls_sha512_update()
    * mbedtls_sha512_finish()
    * mbedtls_sha512_process()
The return codes can be used to return error values. This is important
when using hardware accelerators.
