[PATCH V3] thermal: imx: Add missing of_node_put()

[Anson Huang]

After finishing using cpu node got from of_get_cpu_node(), of_node_put()
needs to be called, the cpufreq policy also needs to be put unconditionally.

Changes since V2:
        - call cpufreq_cpu_put() unconditionally after cooling register done.
