Subject: [PATCH] thermal/of: Initialize the thermal governor for configuring thermal zones.

Configure the initial thermal governor of thermal zones on the device tree.
Since the kernel provides a variety of thermal governors,
to a certain extent,thermal governor is also a specific hardware property
 of thermal zones.
