PCI/MSI: Make the pci_msi_map_rid_ctlr_node() interface firmware agnostic
To support booting with OF and ACPI seamlessly, GIC ITS parent code
requires the PCI/MSI irqdomain layer to implement a function to retrieve
an MSI controller fwnode and map an RID in a firmware agnostic way
(ie pci_msi_map_rid_ctlr_node()).
Convert pci_msi_map_rid_ctlr_node() to an OF agnostic interface
(fwnode_handle based) and update the GIC ITS MSI parent code to reflect
the pci_msi_map_rid_ctlr_node() change.
