arm64: dts: imx8mm-beacon-som: Fix Choppy BT audio
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.
