PCI: don't load acpi_php when acpi is disabled
When acpi=off and pci=nomsi, don't load acpiphp.
Fixes this:
pci_hotplug: PCI Hot Plug PCI Core version: 0.5
acpiphp: ACPI Hot Plug PCI Controller Driver version: 0.5
ACPI Exception (utmutex-0263): AE_BAD_PARAMETER, Thread
FFFF81103CC54000 could not acquire Mutex [1] [20070126]
[akpm@linux-foundation.org: export acpi_pci_disabled for acpiphp.ko]
