x86: intel-mid: Use the new io_apic interfaces

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.
