When streaming bluetooth audio, the sound is choppy due to the
fact that the default baud rate of the HCI interface is too slow
to handle 16-bit stereo at 48KHz.
The Bluetooth chip is capable of up to 4M baud on the serial port,
so this patch sets the max-speed to 4000000 in order to properly
stream audio over the Bluetooth.
