Fix BCM4335 chip crashes caused by BT/WiFI concurrency

 * The stock B+ driver works around chip crash that occurs when WiFi is
   on and BT is enabled/disabled by sending a magic patch to the
   hardware.
 * This patch was not in an external file, so some reverse engineering
   was required to extract it and put it in the correct format.
 * Enable the prepatch and enjoy crash-free Bluetooth :)

Commit by Cyanogenmod to fix BT Wifi lockups on BCM4335 chips, which the G2 has also experienced on the 4.4.2 kernel. Implement this to G2 (Tested and working)

Enable use of two stop bits for Bluetooth

This improves reliability on chips such as BCM4335.
