1. support 40M Wi-Fi when calculate AFH 2. Calculate channel classification according to Host and coex 3. Set BR/EDR/LE coex schm status in controller 4. Only set AFH for BT when WiFi is connected 5. Fix a potential dead lock issue when set AFH 6. Fix WiFi connecting coex schm issue due to periodic timer 7. Complete BT a2dp pause coex schm 8. Increase BT slice when BT a2dp pause in order to receive AVRC event 9. Add more coex schm for BT/BLE
