ARM: dts: msm: reduce VDD_APCC CPR max aging adjustment for msm8996v3

Reduce the VDD_APCC CPR max aging adjustment from 25 mV to 15 mV.
Aging characterization has shown that at most 15 mV of additional
supply voltage is required as the device ages.  Also lower the
open-loop adjustment for each corner by 10 mV (except for
apc1_vreg) for CPR revisions 3 - 7.  The open-loop voltage had
previously been increased by the 25 mV max aging adjustment
amount to ensure that there was room for the closed-loop voltage
to increase based upon aging.  The lower open-loop voltage allows
for LDO operation at a lower voltage which saves power in some
scenarios.
