e6e6b75ad3 psa: Remove MBEDTLS_PSA_CRYPTO_DRIVERS configuration option
The support for the PSA crypto driver interface
is not optional anymore as the implementation of
the PSA cryptography interface has been restructured
around the PSA crypto driver interface (see
psa-crypto-implementation-structure.md). There is
thus no purpose for the configuration options
MBEDTLS_PSA_CRYPTO_DRIVERS anymore.

c9e0ad23c1 Update design document
- Support for PSA_CRYPTO_CLIENT without PSA_CRYPTO_C is out of scope for
now but might be added later (the architecture supports that).
- While we're using a void pointer for md_ctx, we don't need a union
here; the union will be useful only if & when we remove the indirection.

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.
