x86, io_apic: Introduce x86_io_apic_ops.disable()
This function pointer is used to call a system-specific function for disabling the IO-APIC. Currently this is used for IRQ remapping which has its own disable routine. Also introduce the necessary infrastructure in the interrupt remapping code to overwrite this and other function pointers as necessary by interrupt remapping.
