ACPI: Altix: ACPI _PRT support
Provide ACPI _PRT support for SN Altix systems. The SN Altix platform does not conform to the IOSAPIC IRQ routing model, so a new acpi_irq_model (ACPI_IRQ_MODEL_PLATFORM) has been defined. The SN platform specific code sets acpi_irq_model to this new value, and keys off of it in acpi_register_gsi() to avoid the iosapic code path.
