[PATCH 1/2] dt-bindings: soc: qcom: pmic-glink: Document batteryless property

[Rakesh Kota]

Document the "qcom,batteryless" boolean device tree property
for the PMIC Glink battery manager node.

When this property is present, the battery manager driver registers
the power supply as POWER_SUPPLY_TYPE_MAINS instead of BATTERY.
This is intended for 12V DC adapters, where presenting the supply
as a battery would cause userspace to incorrectly trigger battery
power-saving sequences.
