ARM: dts: qcom: Optimize jeita-fcc-step thresholds 

With the current jeita-fcc-step thresholds observing multiple
frequent JEITA entry-exit event while charging with higher
charge current for longer time, When the JEITA condition
is hit, the charge-current is reduced significantly until
the battery temperature drops below sw-jeita-hys threshold
which causes the overall charge time to increase. Optimize
Optimize this by adding some intermediate steps between
10.00A and 1.89A. While at it also change the hysteresis
for the same.
