Zhao Yakui 33a2a529f7 ACPI: Update the t-state for every affected cpu when t-state is changed 
According to ACPI spec, the _TSD object provides T-state control cross
logical processor dependency information to OSPM. So the t-state
coordination should be considered when T-state for one cpu is changed.

According to ACPI spec, three types of coordination are defined.
SW_ALL, SW_ANY and HW_ALL.

SW_ALL: it means that OSPM needs to initiate T-state transition on
all processors in the domain. It is necessary to call throttling set function
for all affected cpus.

SW_ANY: it means that OSPM may initiate T-state transition on any processor in
the domain.

HW_ALL: Spec only says that hardware will perform the coordination and doesn't
recommend how OSPM coordinate T-state among the affected cpus. So it is treated
as the type of SW_ALL. It means that OSPM needs to initiate t-state transition
on all the processors in the domain.
