PCI: Add pci_scan_root_bus_msi()
Add a pci_scan_root_bus_msi() interface so an arch can specify the MSI
controller up front. This removes the need for a pcibios callback to set
the MSI controller later.
This is not exported because I'd like to replace the variety of "scan root
bus" interfaces with a single, more extensible interface that can handle
the MSI controller, domain, pci_ops, resources, etc. I hope this interface
is temporary.
