It is necessary to be added governor at each thermal_zone.
Because some governors should be operated in the during the kernel
booting
in order to avoid heating problem.

Default governor cannot be covered all thermal zones policy because
some thermal zones want to apply different one.
For example, the power allocator governor operates differently with
step wise governor.
Hence, it is better to parse governor parameter from the device tree.

The patch looks okay to me.
Eduardo, what do you think of this patch?

thanks,
