ARM: dts: sun5i: hsg-h702: add axp209 regulator nodes
This patch adds the regulator nodes for the axp209 by including the axp209 dtsi. 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. LDO3 powers the USB WiFi module. This patch also references it from the usb-phy node. Also get rid of axp209 properties already set in axp209.dtsi.
