Subject: [PATCH 0/6] PCI: dwc: Add common pme_turn_off message by using
 outbound iATU

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.                       

Previous two patches is picked from Yoshihiro' big patch serialise.        
 PCI: dwc: Change arguments of dw_pcie_prog_outbound_atu()                 
 PCI: Add INTx Mechanism Messages macros                                   

PCI: Add PME_TURN_OFF message macro                                        
dt-bindings: PCI: dwc: Add 'msg" register region, Add "msg" region to use  
to map PCI msg.                                                            

PCI: dwc: Add common pme_turn_off message method                           
Using common pme_turn_off() message if platform have not define their.
