[PATCH v1 09/14] thermal/core: Put of_node field cooling device structure under Kconfig option

[Daniel Lezcano]

The device node pointer in the cooling device structure is only needed
by the thermal OF in order to bind a thermal zone with a cooling
device. Now only the OF based drivers are using the thermal OF
functions and do not call the function with a NULL device_node
parameter as before. We can put this field under the CONFIG_THERMAL_OF
condition and make it go away if the device tree is not used.
