ARM: dts: msm: Enable APC0/1 CPR closed-loop operation for sdm660 



Configure APC0/1 CPR instances to operate in closed-loop operation
to maintain an optimal voltage set point on the APC0/1 voltage rails.

Also, add static open-loop and closed-loop voltage margins as per
the early voltage characterization results.
