ENGR00220794 imx6 thermal: add suspend and resume for thermal_sys class
1.Avoiding system wrong reboot caused by error temperature without
cancel_delayed_work before entering into suspend,so to cancel
thermal_zone_device temperature polling temperature delayed_work
before entering into suspend, reenable polling temperature delayed_work
after entering into resume.
2.In anatop_thermal_suspend, turn off alarm firstly
