[PATCH 30/41] arm64: dts: qcom: sdm630-xperia-nile: Add all RPM and fixed regulators

[Konrad Dybcio <konrad.dybcio@somainline.org>]

From: AngeloGioacchino Del Regno <angelogioacchino.delregno@somainline.org>

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