ARM: dts: msm: update VDD_GFX CPR aging and loop parameters for msmcobalt

Browse source 
Hardware characterization has shown that a new CPR aging RO
scaling factor is required on MSMCOBALT v2.  Change this value
to match characterization results.  Also specify a CPR count
repeat value of 1 to override the implicit 0 default in order
to improve CPR closed-loop voltage settling stability.
