ChaCha20 (PSA): Document that we only support 12-byte nonces

Support for 8-byte nonces may be added in the future:
https://github.com/ARMmbed/mbedtls/issues/5615

Support for a 16-byte IV for ChaCha20 consisting of a 12-byte nonce and a
4-byte initial counter value may be added in the future:
https://github.com/ARMmbed/mbedtls/issues/5616
