/* When at least one block cipher (AES, ARIA, Camellia) is accelerated, the
* builtin implementation of GCM/CCM calls into legacy gcm/ccm modules first
* and then into block_cipher module. The latter will
* then dispatch to PSA again to encypt data using block ciphers in ECB mode,
* which means we need PSA_WANT_ALG_ECB_NO_PADDING to allow this.
