ACPI : Update T-state coordination after getting _TSD info
Accordint to ACPI spec, the _TSD object provides T-state control cross logical processor dependency information to OSPM. After the _TSD data for all cpus are obtained, OSPM will set up the T-state coordination between CPUs. Of course if the _TSD doesn't exist or _TSD data is incorrect , it is assumed that there is no T-state coordination and T-state is changed independently. Now there is no proper solution to update T-state coordination after one cpu is hotplugged. So this patch won't support hotplugged cpu very well.
