arm64: dts: qcom: x1e80100-dell-xps-9345: Add WiFi/BT pwrseq

Browse Source 
Add the WiFi/BT nodes for XPS and describe the regulators for the WCN7850
combo chip using the new power sequencing bindings. All voltages are
derived from chained fixed regulators controlled using a single GPIO.

Based on the commit d09ab685a8 ("arm64: dts: qcom: x1e80100-qcp: Add
WiFi/BT pwrseq").
