ARM: dts: msm: Disable ADC based AICL for pmi632

Currently, with ADC based AICL settled value, weak adapters keep
collasping, thereby reducing the overall charge current. And, with
ADC based AICL disabled, weak adapters are able to sustain the settled
ICL current without collapsing. Hence, disable ADC based AICL for
pmi632 charger.
