ARM: dts: msm: set APC0/1 CPR QUOT and init-volt adjustments for msm8994v2 



Specify conditional CPR target quotient and initial voltage
adjustment values for VDD_APC0 and VDD_APC1 cpr-regulator devices
on MSM8994 v2 boards.  These adjustments remove excess voltage
margin from the target values used by the APC0 and APC1 CPR
controllers.  This in turn reduces system power consumption.
