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 f94277af03ea ("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.
