If someone correctly describes the gpio_reset as active-low, then the
driver will not work.
If there is any out-of-tree user of the gpio_reset property, they are
passing the incorrect polarity in the device tree
and things are working by pure luck. (wrong polarity in dts + wrong
polarity handling in the driver = working state)
Ok, if this can't be fixed, then let's drop patches 2 and 3, which is
unfortunate.
