commit ca637c0ece144ce62ec8ef75dc127bcccd4f442a upstream.
The reset line is called PWRST#, annotated as "active low" in the binding documentation, and is driven low and then high by the driver to reset the chip. However in device tree for CI20 board it was incorrectly marked as "active high". Fix it.
Because (as far as I know) the ci20.dts is always built in the kernel I elected not to also add a quirk to gpiolib to force the polarity there.
