The chown operation on the cp_temp sysfs attribute needs to happen after
the cp_thermal_zone driver has been loaded by the insmod_sh service.
If not, the owner/group won't be updated and after the driver gets
loaded, cp_temp will default to root/root. Hence, we are moving this
operation from init to the post-fs-data stage.
Test: Verified owner/group for the sysfs attribute
