arm64: dts: qcom: msm8916-samsung-fortuna/rossa: Add fuel gauge

Like the Samsung Galaxy A3/A5, the Grand Prime/Core Prime uses a
Richtek RT5033 PMIC as battery fuel gauge, charger, flash LED and for some
regulators.
For now, only add the fuel gauge/battery device to the device tree, so we
can check the remaining battery percentage.

The other RT5033 drivers need some more work first before they can be used
properly.
