arm64: dts: qcom: qcs8300-ride: enable WLAN on qcs8300-ride

Enable WLAN on qcs8300-ride by adding a node for the PMU module
of the WCN6855 and assigning its LDO power outputs to the existing
WiFi module.

On the qcs8300-ride platform, the corresponding firmware and BDF
are QCA6698AQ instead of WCN6855, which have been added in the
20250211 release.
