wifi: rtw89: coex: add WL_S0 hardware TX/RX mask to allow WL_S0 TX/RX during GNT_BT
WiFi/BT combo module could only have two antenna, namely WL_S0 and WL_S1.
WiFi can use two antenna to TX/RX 2SS data, and BT can share one of the
antenna. This patch is to allow WiFi to TX/RX 1SS data like ACK/RTS/CTS to
improve Wi-Fi performance while coexisting with Bluetooth.
