As the inputs of these regulators are from the axp209's PS output, which is basically just a mux over the 2 inputs, it is considered to be unregulated. Thus we do not provide input supply properties for them. The regulator names and constraints are based on the board schematics and the SoC datasheet. DCDC2 is used as the cpu power supply. This patch also references it from the cpu node. Also get rid of axp209 properties already set in axp209.dtsi.
