Update AES function signatures to use const pointers for parameters that
are not modified. This improves type safety and makes it easier to see
which parameters are read-only.
Fix the Nuvoton npcm_ae driver as well since it implements the API.
Really that should be handled by a driver, but leave that for now.
Functions updated:
- aes_expand_key(): key parameter
- aes_encrypt(): in and expkey parameters
- aes_decrypt(): in and expkey parameters
- aes_apply_cbc_chain_data(): cbc_chain_data and src parameters
- aes_cbc_encrypt_blocks(): key_exp, iv, and src parameters
- aes_cbc_decrypt_blocks(): key_exp, iv, and src parameters
- add_round_key(): key parameter (internal)
- debug_print_vector(): data parameter (internal)
