fad34a4f10 Support all legacy algorithms in PSA 
This is not strictly mandatory, but it helps.

3e30e1fb19 We haven't actually made hash accelerators initless in 3.3 
It seems that it won't be necessary anyway.

14239c6e2e Switching to PSA can break things with MBEDTLS_PSA_CRYPTO_CLIENT 
It's a rare scenario, but it's currently possible: if you use
mbedtls_cipher_xxx() to encrypt the communication between the application
and the crypto service, changing those functions to call PSA will break your
system.

382b34ca84 Work out the hash interface requirements 
Finish working out the RSA-PSS example in terms of what it implies about the
interface. The key takeaway is that a mixed-domain module must support
algorithms if they are available through either interface, and that's all
there is to it. The details of how dispatch is done don't matter, what
matters is only the availability, and it's just the disjunction of
availabilities.
