PCI hotplug: move IOAPIC support from acpiphp to ioapic driver
This patch moves PCI I/O APIC support from acpiphp to a separate driver. Like pciehp and shpchp, acpiphp handles PCI hotplug, i.e., addition and removal of PCI adapters. But in addition, acpiphp handles some ACPI hotplug, such as the addition of new host bridges, and the I/O APIC support was tangled up with that. I don't think the I/O APIC support needs to be in acpiphp; PCI I/O APICs usually appear as a function on a PCI host bridge, and we'll enumerate the APIC before any of the devices behind the bridge that use it. As far as I know, nobody actually uses I/O APIC hotplug. It depends on acpi_register_ioapic(), which is only implemented for ia64, and I don't think any vendors have supported I/O chassis hotplug yet.
