arm64: dts: qcom: sc8280xp-arcata: model the PMU of the on-board wcn6855

Browse source

Align the Surface Pro 9 5G with the other sc8280xp-based models as done in
this patch series [1] from Bartosz.

Add a node for the PMU of the WCN6855 and rework the inputs of the wifi
and bluetooth nodes to consume the PMU's outputs.

With this we can drop the regulator-always-on properties from vreg_s11b
and vreg_s12b as they will now be enabled by the power sequencing
driver.

Use the fixed BT vddrfa1p7-supply supply name to align with bindings.
