[PATCH rtw-next 6/6] wifi: rtw89: pack I/O during RF nctl init to reduce execution time

[Ping-Ke Shih <pkshih@realtek.com>]

From: Johnson Tsai <wenjie.tsai@realtek.com>

Wrap the register writes of rtw89_phy_init_rf_nctl() with
rtw89_io_pack/unpack so they are batched into single bus transactions,
reducing API execution time.

8852C USB2.0 AMD B450 initialization time:
    rtw89_phy_init_rf_nctl                  5355 ms -> 10 ms
