thermal: intel: pch: move cooling delay to suspend_noirq phase
Move the PCH Thermal driver suspend callback to suspend_noirq to do cooling while the system is more quiescent. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Tested-by: Sumeet Pawnikar <sumeet.r.pawnikar@intel.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
