ARM: dts: msm: reduce VDD_APCC voltage margin for aging on msm8996v3 



Reduce the VDD_APCC open-loop voltage margin by 15 mV and the
closed-loop voltage margin by 10 mV for power cluster and
performance cluster corners corresponding to less than 600 MHz.

Also, reduce the VDD_APCC open-loop voltage margin by 15 mV and
the closed-loop voltage margin by 10 mV for all CBF clock
corners.

This removes the voltage margin associated with aging and allows
lower VDD_APCC operating voltage are parts that are not aged.
