The irqdomain creation that is carried out in: platform_msi_create_device_domain() relies on the fwnode_handle interrupt controller token to associate the interrupt controller with a specific irqdomain. Current code relies on the OF layer to retrieve a fwnode_handle for the device representing the interrupt controller from its device->of_node pointer. This makes platform_msi_create_device_domain() DT specific whilst it really is not because after the merge of commit f94277af ("of/platform: Initialise dev->fwnode appropriately") the fwnode_handle can easily be retrieved from the dev->fwnode pointer in a firmware agnostic way. Update platform_msi_create_device_domain() to retrieve the interrupt controller fwnode_handle from the dev->fwnode pointer so that it can be used seamlessly in ACPI and DT systems.
