Series wifi: rtl8xxxu: Add concurrent mode for 8188f | expand

Commit Message

Martin Kaistra Dec. 22, 2023, 10:14 a.m. UTC 
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.
