ANDROID: thermal: Add vendor thermal_pm_notify_suspend function

Browse Source 
Currently, most of the thermal_zones are IRQ capable and they do not need
to be updated while resuming. To improve the system performance and reduce
the resume time. Add a vendor function to check if the thermal_zone is
not IRQ capable and needs to be updated.

Bug: 170905417
Bug: 336700210
Bug: 332221925
Test: boot and vendor function worked properly.
