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.
