f87e3aea16 Update guards in PSA crypto library for ECDSA and DETERMINISTIC support
In the PSA crypto library, the code for verification of ECDSA is the same for
both MBEDTLS_PSA_BUILTIN_ALG_ECDSA and
MBEDTLS_PSA_BUILTIN_ALG_DETERMINISTIC_ECDSA. So, the guards should allow for
either one to enable the code blocks. The original implementation only had
the check for ECDSA. In order to make this work, config_psa.h was updated
to ensure when MBEDTLS_CRYPTO_CONFIG is disabled, the setting for DETERMINISTIC
is only updated if MBEDTLS_ECDSA_C is also enabled.

Ensure that MBEDTLS_ECDSA_C is set when PSA_WANT_ALG_DETERMINISTIC_ECDSA

4377bf7479 Added new PSA crypto config test with no test driver
Added a new test to all.sh to confirm that using MBEDTLS_PSA_CRYPTO_CONFIG
with no test driver and the library is configured with normal configurations
that the test works.

Minor updates to other PSA crypto tests to cleanup msg output for consistency.

6dff93ff9b Ensure dependent features also included by config_psa.h
When the PSA crypto features need to be setup based on the
PSA_WANT_xxx macros, the dependent features also need to be
enabled. This change corrects that for the MBEDTLS_ECDSA_DETERMINISTIC.

28baa1f141 Fixed test_psa_want_ecdsa_disabled_software to use proper macros
Updated the test_psa_want_ecdsa_disabled_software to enable and disable
the correct macros to accomplish the desired test. The previous version
left out the disabling of additional macros to ensure items related
to MBEDTLS_ECDSA_C were also unset. The test was also missing the setting
of the accelerators MBEDTLS_PSA_ACCEL_ALG_ECDSA and DETERMINISTIC_ECDSA.

With the accelerators enabled the test portion had to be temporarily
disabled until the accelerator code is completed so the test will work
properly.

Updated the signature driver source to fix a compiler warning when
MBEDTLS_ECDSA_C is unset.

0ea39e0ee4 Correct use of MBEDTLS_PSA_BUILTIN_ALG_xxx in crypto library
The psa crypto library was generically using PSA_WANT_ALG_xxx, but
should have been using the correct MBEDTLS_PSA_BUILTIN_ALG_xxx
definition since that code is the builtin version. There were also
a couple of spots that needed to ensure the code block was enabled
for either ECDSA or DETERMINISTIC_ECDSA, not just one of them.

Fixed all the new ALG_ECDSA_DETERMINISTIC names to be
ALG_DETERMINISTIC_ECDSA instead.

Fixed test to use correct definitions.

7b453130e2 Updates to fix check-names and all.sh tests after review
Need to make sure the new MBEDTLS_PSA_ACCEL_XXX defines are not checked
since they should be defined by the PSA driver. Updated the list-macros.sh
script to modify the instances of those found to match the corresponding
MBEDTLS_PSA_BUILTIN_XXX that are defined in config_psa.h

Fixed definition of MBEDTLS_PSA_BUILTIN_ALG_ECDSA_DETERMINISTIC, name was
incorrect. Also fixed a missing space in the comments of crypto_config.h

test_psa_want_ecdsa_disabled_software so it is more clear and

MBEDTLS_PSA_ACCEL_ALG_ECDSA since it should not have been used

This new description makes it clear that the file should not be edited

otherwise the MBEDTLS_XXX should be set.

714e3a1318 Minor cleanup to fix errors with some unit tests
With the new feature MBEDTLS_PSA_CRYPTO_CONFIG, needed to
add support that when the feature is disabled, if there
are defines like MBEDTLS_ECDSA_C defined, then the PSA_WANT_
equivalent define is also enabled. This ensures the guards in
the library psa_crypto will work properly.

Also fixed an error return code in the driver wrapper for cipher
encrypt setup so it will properly pass unit tests.

Ensured config.py full works properly with the new
MBEDTLS_PSA_CRYPTO_CONFIG, it should not be set when the full
option is used.

2dfaf9ca23 Update how MBEDTLS_PSA_CRYPTO_CONFIG is handled
Originally, MBEDTLS_PSA_CRYPTO_CONFIG was being used to allow
inclusion of mbedlts/config_psa.h, but that needed to be updated
so that mbedtls/config_psa.h is always included and the definitions
specific to PSA configuration are now guarded by
MBEDTLS_PSA_CRYPTO_CONFIG. This will allow for the standard setup
to continue working while new PSA configuration items to also work.
