Enable BT on qcs8300-ride by adding a node for the BT module. Since the
platform uses the QCA6698 Bluetooth chip. While the QCA6698 shares th
same IP core as the WCN6855, it has different RF components and RAM sizes,
requiring new firmware files. Use the firmware-name property to specify
the NVM and rampatch firmware to load.
