[PATCH] x86: intel-mid: fix watchdog platform code

[David Cohen <david.a.cohen@intel.com>]

This patch fixes missing include asm/io_apic.h which may lead to
following error:

   arch/x86/platform/intel-mid/device_libs/platform_wdt.c: In function 'tangier_probe':
>> arch/x86/platform/intel-mid/device_libs/platform_wdt.c:37:2: error: implicit declaration of function 'mp_find_ioapic' [-Werror=implicit-function-declaration]
     ioapic = mp_find_ioapic(irq);
     ^
>> arch/x86/platform/intel-mid/device_libs/platform_wdt.c:44:3: error: implicit declaration of function 'io_apic_set_pci_routing' [-Werror=implicit-function-declaration]
      ret = io_apic_set_pci_routing(NULL, irq, &irq_attr);
      ^
