acpi: pci: Setup MSI domain for ACPI based pci devices
This patch introduces pci_msi_register_fwnode_provider() for irqchip
to register a callback, to provide a way to determine appropriate MSI
domain for a pci device.
It also introduces pci_host_bridge_acpi_msi_domain(), which returns
the MSI domain of the specified PCI host bridge with DOMAIN_BUS_PCI_MSI
bus token. Then, it is assigned to pci device.
