In some intel-mid platforms (Medfield/Merrifield etc), the IOAPIC
may have more than 80 pins, and some devices like a i2c based touch
screen has its interrupt line directly connected to IOAPIC (this
platform_wdt.c here should be the same case).
Since these devices are not PCI device or ACPI device, they can't
use the general PCI/ACPI xxx_enable_dev APIs which implicitly set
up the ioapic entry, but use this "io_apic_set_pci_routing"
directly.
Thanks,
Feng
