Doesn't do much but provided the detection path for it and ability to hold initialized state. The higher level platform code is going to need to use it directly so will mostly just provide an api for access to it. Moved ACPI sniffing back to just after the VM is initialized instead of all the way into platform_init(). This should try to ensure that all drivers that come up afterwards will have ioapics discovered in case future development tries to enable and use them, kicking the machine out of virtual-wire-mode.
