[PATCH 29/39] arm64: dts: qcom: sdm630-xperia-nile: Add all RPM and fixed regulators

From: Konrad Dybcio
Date: Wed Jul 28 2021 - 18:27:02 EST

From: AngeloGioacchino Del Regno <angelogioacchino.delregno@xxxxxxxxxxxxxx>

Add all of the RPM PM660/PM660L regulators and the fixed ones,
defining the common electrical part of this platform.
