[PATCH 05/15] arm64: dts: mediatek: radxa-nio-12l: Configure board regulators

From: AngeloGioacchino Del Regno
Date: Fri Jan 12 2024 - 04:48:01 EST

Add the entire power tree, which also includes all of the voltage
regulators found on all of the PMICs and fixed vregs on this board.
While at it, also add the two MT6315 PMICs over SPMI, providing
CPU-Big and GPU power rails.
