If the reset gpio polarity is different, please change it in the DT by using
a different gpio flag instead of changing the driver.

However if the logic is different and reset must never be asserted to low,
the the bindings + driver to make the reset line optional and set a gpio-hog
in DT to keep it at a safe level.
