ARM: dts: msm: Enable APC0/1 CPR closed-loop operation for sdm630
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 voltage characterization results.
