wifi: rtw89: pack I/O during bb_sethw to reduce API execution time
Wrap rtw89_chip_bb_sethw() with rtw89_io_pack/unpack so all register writes during baseband hardware initialization are batched into a single bus transaction. This reduces API execution time from ~11000 us to ~4000 us on affected platforms.
