ieee802154: rename struct ieee802154_addr to *_sa
The struct as currently defined uses host byte order for some fields, and most big endian/EUI display byte order for other fields. Inside the stack, endianness should ideally match network byte order where possible to minimize the number of byteswaps done in critical paths, but this patch does not address this; it is only preparatory.
