dt-bindings: hwmon: (ina3221) Add ti,single-shot property

By default, ina3221, as a hardware monitor, continuously measures
the inputs and generates corresponding data. However, for battery
powered devices, this mode might be power consuming.

This patch adds a "ti,single-shot" property to allow changing the
default continuous mode to single-shot operating mode.

Optional properties:
- ti,single-shot: This chip has two power modes: single-shot (chip takes one
measurement and then shuts itself down) and continuous (
chip takes continuous measurements). The continuous mode is
more reliable and suitable for hardware monitor type device,
but the single-shot mode is more power-friendly and useful
for battery-powered device which cares power consumptions
while still needs some measurements occasionally.
If this property is present, the single-shot mode will be
used, instead of the default continuous one for monitoring.
