From: John Crispin <john@xxxxxxxxxxx>
MediaTek produces various PMICs. Which one is used depends on the actual
circuit design. Instead of adding the correct PMIC node to every dts file
we instead add a new intermediate dtsi file which adds the PMIC node.
Additionally we also add the phandles for the regulators to various nodes.
