ARM: dts: msm: update VDD_GFX CPR voltage margins for msm8996v3 



Update the CPR open-loop and closed-loop voltage margins for each
VDD_GFX corner for MSM8996 v3.0 and v3.1 chips in order to match
the most recent hardware characterization results.  This ensures
stable operation across all parts and saves power where possible.

Also update the VDD_GFX MinSVS target quotients for MSM8996 v3.1
in order to match the characterized values.
