gpio-line-names gets defined in devicetree/bindings/gpio/gpio.txt
which isn't converted to yaml yet:

Optionally, a GPIO controller may have a "gpio-line-names" property. This is
an array of strings defining the names of the GPIO lines going out of the
GPIO controller.


So that property is perfectly fine where it is.
