[PATCH 11/15] arm64: dts: qcom: msm8994-kitakami: Update regulator configuration

Konrad Dybcio
2022-03-19T17:47:47Z

Remove regulator-always-on property where not necessary and mark regulators
that are not supposed to be voted active on boot with regulator-boot-on.
While at it, reorder the load properties to make it look more decent.

Reorder PMICs to fix a probe defer caused by messy dependencies and Linux's
inability to handle them (at least for now).
