msm: thermal: Configure core sensor id on emergency frequency init

Core sensor id is configured during emergency hotplug initialization
and the same id is used for emergency frequency mitigation. This
dependency will break emergency frequency mitigation feature,
if emergency frequency mitigation is enabled and emergency hotplug
is not. Configure core sensor id during emergency mitigation
initialization as well to avoid this scenario.
