ARM: dts: msm: update step-jeita and step-charging thresholds

Current thresholds of step-jeita and step-charging keeps a buffer
between Max. threshold of current step and Min. threshold of next step,
this leads to failure if step parameter falls between Max. and Min.
thresholds of two steps. Fix this by updating Min. threshold of all the
steps same as Max. threshold of previous step.
