ARM: dts: qcom: msm8974-klte: Add fuel gauge

Browse source 
The Samsung Galaxy S5 uses a maxim17048 fuelgauge. The maxim,rcomp value
is taken from downstream kernel. Model data and temperature-based
compensation are not yet supported in the mainline driver, but the
readings seem fine nevertheless.
