arm64: dts: qcom: qcs8300-ride: Enable Bluetooth support

Enable BT on qcs8300-ride by adding a BT device tree node.

Since the platform uses the QCA6698 Bluetooth chip. While
the QCA6698 shares the 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.
