Yinghai Lu 857fdc53a0 x86/pci: insert ioapic resource before assigning unassigned resources 
Stephen reported that his DL585 G2 needed noapic after 2.6.22 (?)

Dann bisected it down to:
  commit 30a18d6c3f
  Date:   Tue Feb 19 03:21:20 2008 -0800

      x86: multi pci root bus with different io resource range, on
      64-bit

It turns out that:
  1. that AMD-based systems have two HT chains.
  2. BIOS doesn't allocate resources for BAR 6 of devices under 8132 etc
  3. that multi-peer-root patch will try to split root resources to peer
     root resources according to PCI conf of NB
  4. PCI core assigns unassigned resources, but they overlap with BARs
     that are used by ioapic addr of io4 and 8132.

The reason: at that point ioapic address are not inserted yet.  Solution
is to insert ioapic resources into the tree a bit earlier.
