[PATCH] x86: fix the irqbalance quirk for E7320/E7520/E7525
Move the irqbalance quirks for E7320/E7520/E7525(Errata 23 in http://download.intel.com/design/chipsets/specupdt/30304203.pdf) to early quirks. And add a PCI quirk for these platforms to check(which happens very late during the boot) if the APIC routing is indeed set to default flat mode. This fixes the breakage(in x86_64) of this quirk due to cpu hotplug which selects physical mode instead of the logical flat(as needed for this errata workaround).
