[ Upstream commit db030c5a9658846a42fbed4d43a8b5f28a2d7ab7 ]
The Bluetooth chip is capable of operating at 4Mbps, but the max-speed setting was on the UART node instead of the Bluetooth node, so the chip didn't operate at the correct speed resulting in choppy audio. Fix this by setting the max-speed in the proper node.
