Subject: [PATCH 09/21] wifi: rtl8xxxu: support setting bssid register for
multiple interfaces
To prepare for concurrent mode, enhance rtl8xxxu_set_bssid() to write the
BSSID of the respective interface to REG_BSSID or REG_BSSID1.
Like done with rtl8xxxu_set_mac(), call rtl8xxxu_set_bssid() with
port_num = 0, until the callers also support multiple interfaces.
