1. fix BLE connection missing in coex mode 2. modify other parameters to make coex priority more reasonable 3. fix modem sleep procedure trap cause Wifi disable RF when BT is working. Such cause that BR/EDR is difficult to be connected, BLE connection stability decrease and so on. 4. modify BR/EDR coexist duration to imrove BR/EDR connect success ratio. 5. Due to the hardware coexist bug, BLE scan interval/window should be less than 0x100(about 160ms). Therefore, it will cause BLE cannot scan any advertising packet while WiFi have higher priority behaviour(such like RX beacon, scan, TX/RX VO packets and etc.).
