    x86, irq: Make MSI and HT_IRQ indepenent of X86_IO_APIC

    Now we have splitted functions to support MSI and HT_IRQ into vector.c,
    and they have no dependency on IOAPIC any more. So change Kconfig files
    to make MSI and HT_IRQ independent of X86_IO_APIC.

    This allows native hypertransport devices to use interrupts.
