drivers: thermal: Add support to modify passive/polling delay to of_thermal 



Whenever userspace modifies thermal zone passive delay or polling
delay from sysfs, of_thermal can reset this value to devicetree
defaults while re-enabling thermal zone. Add support to update
passive delay and polling delay to the of_thermal framework so that
userspace can modify and retain the delay across multiple disable
and enable actions.
