lm-senser can't detect thermal on thermal_zone

[Kuninori Morimoto]

Hi Zhang, Eduardo

Our platform now is using thermal_zone, but lm-senser became no longer working.
It works on non thermal_zone. we can get current thermal from
/sys/class/thermal/thermal_zone0 on thermal_zone.
What does lm-senser is doing ? and why it doesn't work on thermal_zone ??
