  Involve an new and common mathod to send pme_turn_off() message. Previously
pme_turn_off() implement by platform related special register to trigge    
it.                                                                        
                                                                           
But Yoshihiro give good idea by using iATU to send out message. Previously 
Yoshihiro provide patches to raise INTx message by dummy write to outbound 
iATU.                                                                      
                                                                           
Use similar mathod to send out pme_turn_off message.
