PCI: endpoint: Add RC-to-EP doorbell support using platform MSI controller
Implement the doorbell feature by mapping the EP's MSI interrupt controller
message address to a dedicated BAR.
The EPF driver should pass the actual message data to be written to the
message address by the host through implementation-specific logic.
