ARM: dts: msm: enable APC CPR closed-loop operation for sdm632 



Enable APC CPR HW closed-loop operation with multi-thread
configuration. Silver cluster and CCI sensors are mapped
to thread-0 and Gold cluster sensors are mapped to Thread-1.
CPR controller aggregates the individual thread recommendations
and update the rail voltage through CCI-SAW4 AVS interface.

Also, configure CPR consecutive down parameter to 0 for both
the threads to fix the thread aggregation logic.

Also, configure CPR controller to keep thread vote always
enabled.
