Subject: [PATCH] ARM: dts: msm: update VDD_GFX CPR parameters for msmcobalt

Update these CPR closed-loop configurations parameters based upon
the most recent hardware guidelines: the per-corner voltage
adjustments, the fused adjustment corner mapping, and the CPR
count mode.  Also, add place holder 0 uV per-fused-corner
open-loop voltage adjustments.
