ARM: dts: msm: update the VIN_MIN value for MSM8916

The PM8916 LBC relies on the VIN_MIN loop to turn off the power FET
when charger removed. It is important to make sure the VIN_MIN setting
value is higher than the VDD_MAX. The VIN_MIN should be set to 100mV
above VDD_MAX so that we could detect the charger removal. The VDD_MAX
value is 4200mv for MTP and 4350mv for SKUH board. The nearest available
VIN_MIN is 4308mv for MTP and 4470mv for SKUH.
