arm64: dts: qcom: x1e80100-qcp: Add WiFi/BT pwrseq

Browse source

Add the WiFi/BT nodes for QCP 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.

The same setup also works for CRD (and likely most of the other X1E80100
laptops). However, unlike the QCP they use soldered or removable M.2 cards
supplied by a single 3.3V fixed regulator. The other necessary voltages are
then derived inside the M.2 card. Describing this properly requires
new bindings, so this commit only adds QCP for now.
