CRACEN: Avoid "unused function" for cracen_aead_update_internal

frkv · rlubos · commit 3985034c7d3f · 2025-08-19T12:29:08.000+02:00
-Add __maybe_unused to cracen_aead_update_internal to try to turn off
 -Wno-unused-function in nrf_security. This function is __maybe_unused
 because some usages of AEAD is single shot. Note that there is
 no configuration to signal whether you support only single shot
 AEAD in PSA crypto (only PSA_WANT_ALG_CCM, PSA_WANT_ALG_GCM etc.)

 See sdk-nrf PR-22619 for details
