ARM: dts: msm: specify VDD_APCC CPR voltage adjustments for msm8996 



Device characterization has shown that some of the fused
open-loop voltages and target quotients for VDD_APCC on msm8996
need adjustment in order to ensure optimal voltage margin for
all corners.

Specify ring oscillator scaling factors, open-loop voltage
adjustments, and closed-loop voltage adjustments which match
the characterization data.
