The goal of this issue is to add the p256m driver in psa-crypto.
List of tasks to be done (may not be comprehensive):
[ ] Add copy of directory p256m into drivers/p256m
[ ] Add a drivers/CMakeLists.txt similar to the 3rdparty/CMakeLists.txt one (only p256m, not everest)
[ ] Add a drivers/p256m/CMakeLists.txt (do we need to install the p256m includes as in mbedtls?)
[ ] In core/CMakeLists.txt add two target_link_libraries( ... PRIVATE p256m) like in library/CMakeLists.txt (not PUBLIC p256m but PRIVATE p256m though I'd say).
[ ] Add PSA_CRYPTO_P256M_DRIVER_ENABLED config option and its documentation in the section "PSA driver interface implementation configuration options" of crypto_config.h. Similar to MBEDTLS_PSA_P256M_DRIVER_ENABLED in mbedtls. Disabled by default.
[ ] Add its translation to MBEDTLS_PSA_P256M_DRIVER_ENABLED in config_adjust_mbedtls_from_psa_crypto.h.
[ ] Add a test_ccm_aes_sha256_secp256r1_p256m test component based on the configs/ccm-aes-sha256-secp256r1.h reference configuration with PSA_CRYPTO_P256M_DRIVER_ENABLED enabled similar to the test_tfm_config_p256m_driver_accel_ec test component in mbedtls.
[ ] Check that the test component do what it intends to do and give evidence of this in this issue or the associated PR for the benefit of reviewers.
