Crypto Callback Build Options:
 * WOLF_CRYPTO_CB:      Master enable for crypto callback       default: off
 *                      framework. Required for all options below.
 * WOLF_CRYPTO_CB_FIND: Enable find device callback functions   default: off
 *                      Allows lookup of registered crypto devices.
 * WOLF_CRYPTO_CB_CMD:  Enable command callbacks invoked during default: off
 *                      register and unregister of crypto devices.
 * WOLF_CRYPTO_CB_COPY: Enable copy callback for algorithm      default: off
 *                      structures (hash, cipher state copying).
 * WOLF_CRYPTO_CB_FREE: Enable free callback for algorithm      default: off
 *                      structures (cleanup of crypto objects).
 * WOLF_CRYPTO_CB_AES_SETKEY: Enable callback for AES key setup default: off
 * WOLF_CRYPTO_CB_RSA_PAD: Enable callback for RSA padding      default: off
 *                      operations (custom padding handling).
 * DEBUG_CRYPTOCB:      Enable debug InfoString functions        default: off
 *
 * Device ID options:
 * WC_USE_DEVID:        Specify a default device ID to use      default: off
 *                      when no hardware device is detected.
 * WC_NO_DEFAULT_DEVID: Disable automatic default device ID     default: off
 *                      selection. Requires explicit devId passing.
 * WOLFSSL_CAAM_DEVID:  Device ID constant (value 7) for NXP    default: off
 *                      CAAM hardware crypto.
 *
 * Algorithm-specific callback options:
 * NO_SHA2_CRYPTO_CB:   Disable crypto callbacks for SHA-384    default: off
 *                      and SHA-512 operations.
 * WOLF_CRYPTO_CB_NO_SHA512_FALLBACK:                           default: off
 *                      Do not fall back to the generic SHA-512
 *                      callback for SHA-384, SHA-512/224 and
 *                      SHA-512/256 when no variant-specific
 *                      callback is registered. Required for
 *                      backends whose hash context has no
 *                      digest[] state field or that keep the
 *                      hash state on the device (auto-enabled
 *                      for Renesas FSPSM).
 * WOLF_CRYPTO_CB_ONLY_ECC: Use only callbacks for ECC          default: off
 * WOLF_CRYPTO_CB_ONLY_RSA: Use only callbacks for RSA          default: off
 * WOLF_CRYPTO_CB_ONLY_SHA256: Use only callbacks for SHA-256   default: off
 * WOLF_CRYPTO_CB_ONLY_SHA512: Use only callbacks for SHA-512   default: off
 * WOLF_CRYPTO_CB_ONLY_AES: Use only callbacks for AES          default: off
 * WOLF_CRYPTO_CB_ONLY_ED25519: Use only callbacks for Ed25519  default: off
 * WOLF_CRYPTO_CB_ONLY_CURVE25519: Use only callbacks for X25519 default: off
