wl1271: add gpio_power file in debugfs to power the chip on and off
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.
