Subject: [PATCH v2 3/3] arm64: dts: qcom: msm8916-longcheer-l8150: Add
 battery and charger

Longcheer L8150 doesn't have any dedicated fuel-gauge or charger,
instead making use of the pmic hardware blocks for those purposes.

Add pm8916 bms and charger, as well as the battery cell description
that those blocks rely on.
