      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.
