Subject[Patch] x86: intel-mid: fix conflicts between 78a3bb9e408b and 9f354b0252b8
Date
Commit 9f354b0252b8 "x86, irq: Clean up unused IOAPIC interface" kills
interface io_apic_set_pci_routing(), so change arch/x86/platform/
intel-mid/device_libs/platform_wdt.c to use new interfaces.

Due to hardware resource restriction, this patch only passes compilation
without functional tests.
