Subject: [PATCH v1 1/1] arm64: dts: qcom: sa8775p-ride: Add firmware-name in BT node

The sa8775p-ride 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.
