ARM: dts: msm: enter Wipower ICL ranges for MTP8994



The PMI8994 separates the input current limit (ICL) into three
discrete operating ranges:
When the stark is in pass through mode
When the stark is in div2 mode with DCIN voltage  < 6.5V
When the stark is in div2 mode with DCIN voltage  > 6.5V

These three modes cover the entire range of DCIN voltage but only have
three entries for ICL. This may lead to unoptimized power draw if the
operating voltage falls at the lower side of the range.

A sw algorithm was introduced to reprogram the ICL based on the input
voltage and the div2 signal. Provide the voltage range and ICL data
for this sw algorithm.
