ARM: dts: msm: update CPUSS LDO mode Vref scaling equations for msm8996v3 



Update the LDO functional and retention scaling equations to
match the latest characterization data of msm8996v3 hardware.
This is necessary to ensure stable operation across all parts
when using DCVS set points that enable active LDO mode.
