thermal/core: Make cooling device OF node conditional on CONFIG_THERMAL_OF

Browse source

The device node pointer stored in struct thermal_cooling_device is
only used by the OF-specific thermal code to associate cooling devices
with thermal zones defined in device tree.

Now that OF and non-OF registration paths are separated and non-OF
users no longer rely on devm_thermal_of_cooling_device_register() with
a NULL device node, the np field is no longer required for non-OF
configurations.

Make this field conditional on CONFIG_THERMAL_OF to reduce memory
footprint and better reflect its usage.
