msm: cpr-regulator: add support for high turbo ceiling voltage 



Current design to use fixed ceiling voltage for the chip is not
flexible when the chip could support higher speed/voltage bin.
Add a property to pass initial turbo voltages so that
the driver could see and support higher ceiling voltage.
