The ASPEED HACE model only emulated the hash command; the crypto (cipher)
command was stubbed out. On the AST2700 the kernel runs the crypto driver
self-tests at boot, so without crypto emulation booting floods the log
with failures:

This series implements the HACE crypto command: AES/DES/3DES in ECB/CBC/CTR
over direct and scatter-gather DMA, and AES-GCM with 64-bit DMA on the
AST2700. It also adds GCM to the qcrypto cipher API (gcrypt backend) that
the AST2700 path needs, plus qtest and unit-test coverage.
With crypto emulated the self-tests pass, the warnings above disappear, and
the temporary 'cryptomgr.notests=1' boot workaround in the AST2700
functional tests is dropped.
v1:
1. Support the crypto command in direct access mode
2. Support scatter-gather mode for the crypto command
3. Support the AES-GCM mode for the crypto command
4. Support 64-bit DMA for the crypto command
5. Test the crypto command
6. Drop the AST2700 crypto self-test/model workaround
v2:
1. Add AES-GCM to the nettle and gnutls crypto backends
2. Skip crypto tests for cipher modes the
compiled backend does not support, via qcrypto_cipher_supports()
3. Check qcrypto_cipher_supports() before running a
crypt command and report the mode as unimplemented when the backend lacks it
Note: the gnutls crypto backend does not support CTR mode.
