VPH_PWR is obtained by vonverting 12v voltage into 3.8 voltage with a
3.8v buck. VPH_PWR is power supply for regulators in AIM300 SOM.
VPH_PWR regulator is defined in AIM300 SOM dtsi file.

The regulators in pm8550, pm8550ve and pm8550vs are present on the SoM.
The regulators in pm8010 and pmr73d are present on the carrier board.
In the next version patch series, pm8010 and pmr73d will be moved from
SOM dtsi to carrier board dts file.
