Introduce monitoring behavior changes for USI devices (2/n)
- USI devices are always expected to report a UEvent whenever the
battery state changes. This signals that the current stylus battery
level has changed. This means we should only consider the USI battery
state as valid when we receive a new UEvent.
- Once a stylus battery has been reported, the sysfs battery node will
report the last value perpetually, until the next change, even if the
stylus is no longer being used. To handle this, we set a validity
period, where the USI battery is only valid for a fixed time period
(one hour) after the last time the battery changed.
