ARM: dts: msm: Update QUSB PHY VDD's min value to allow SVS on MSM8996 



Currently QUSB PHY VDD is using nominal voltage when USB is used
in device and host mode. This change starts using SVS voltage with
QUSB PHY VDD voltage supply to allow SVS when USB is cable
connected (both in host and device mode) on MSM8996.
