The property used to specify a GPIO intended for reset is "reset-gpios", this binding uses "gpio-reset", as almost all other bindings use the former name this use of the latter was certainly not intended. It is not compatible with newer methods used to fetch GPIO pins and to prevent the spread of this error to other bindings lets fix this here.
We also standardize the pin as active-low, different device trees have marked the GPIO different ways, luckily the driver currently uses the low-level GPIO set function which does not respect the active-low flag, but future changes may change this. This is an active-low reset, mark it as such.
Lastly, add an example of use for this property.
