acpi/gsi: Add acpi_set_irq_model to initialize the GSI layer
In order to start embrassing irqdomains at the GSI level, introduce a new initializer: void acpi_set_irq_model(enum acpi_irq_model_id model, struct fwnode_handle *fwnode); where: - model is the value assigned to acpi_irq_model - fwnode is the identifier for the irqdomain mapping GSI interrupts As nobody calls this code yet, the current code is (mostly) left in place.
