Subject: [PATCH] thermal/core: associate device tree node to thermal_cooling_device::device
When adding a gpio property to a cooling device node in device tree, then in
thermal driver called gpiod_get(struct device *) to request this gpio will
fail, indicate cannot find gpio in device tree, because the of node do not
associate to struct device.
