As the only user of drivers/acpi/gsi.c is now using acpi_set_irq_model
to set acpi_gsi_domain_id to something meaningful, we can always rely
on that information to be present (its absence is an error), and
guarantee that new interrupt controllers will use this API.
Take this opportunity to cleanup acpi_register_gsi.
