Yinghai Lu 18dce6ba5c x86: Fix SCI on IOAPIC != 0
Thomas Renninger <trenn@suse.de> reported on IBM x3330

booting a latest kernel on this machine results in:

PCI: PCI BIOS revision 2.10 entry at 0xfd61c, last bus=1
PCI: Using configuration type 1 for base access bio: create slab <bio-0> at 0
ACPI: SCI (IRQ30) allocation failed
ACPI Exception: AE_NOT_ACQUIRED, Unable to install System Control Interrupt handler (20090903/evevent-161)
ACPI: Unable to start the ACPI Interpreter

Later all kind of devices fail...

and bisect it down to this commit:
commit b9c61b7007

    x86/pci: update pirq_enable_irq() to setup io apic routing

it turns out we need to set irq routing for the sci on ioapic1 early.

-v2: make it work without sparseirq too.
-v3: fix checkpatch.pl warning, and cc to stable
