dt-bindings: power: supply: max17042: describe interrupt
The Maxim 17042-family of fuel gauges are often embedded in other Maxim
chips, e.g. in Maxim 77693 which is a companion power management IC.
In such designs there might be actually two interrupts:
- INTB signaling change from charger, flash or MUIC,
- ALERT signaling change from fuel gauge.
Describe the interrupt in bindings to make it clear it is about the fuel
gauge ALERT interrupt, not the INT.
