Some debugging tools require the chip to be powered on before they can work. With these tools, we shouldn't upload the firmware nor boot the firmware ourselves, so this debufs file is provided. It always contains the gpio power setting (0 = off, 1 = on). To change the power setting, just write 0 or 1 to the file.
