This will be a regression for people don’t use WiFi.

Do you see "Set BT/WLAN RX diversity capability” in dmesg? Your wireless
chip doesn’t support bt_ant_diversity if you don’t see this message.

BT antenna diversity won’t get set when btcoex_enable is 1. So both
bt_ant_diversity=[0,1] have the same effect.

Judging from the comment, bt_ant_diversity is what we want, to let WiFi
use two antennas when BT is off.

IIUC, this will let WiFi uses single antenna all the time. Not something
user really want.
