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.
