ARM: dts: msm: Enable APC CPR closed loop operation for 8952 



Enable the APC CPR controller to control the VDD_APC voltage.
Enable quotient scaling for NOMINAL operating mode.
Use open-loop voltages as ceiling voltage limits.
Update the floor voltage limit for Turbo operating mode.
Apply 40mV static reduction for the parts with CPR revision
bits fused as '1'.
