Optional property that sets the EN/PB/VSENSE pin to be a
power-button.
TPS65219 has a multipurpose pin called EN/PB/VSENSE that can be either
1. EN in which case it functions as an enable pin.
2. VSENSE which compares the voltages and triggers an automatic
on/off request.
3. PB in which case it can be configured to trigger an interrupt
to the SoC.
ti,power-button reflects the last one of those options
where the board has a button wired to the pin and triggers
an interrupt on pressing it.
