[PATCH] i386/x86-64: Make all early PCI scans dependent on CONFIG_PCI

This is useful on systems with broken PCI bus. Affects various scans in x86-64 and i386's early ACPI quirk scan. Cc: gregkh@suse.de Cc: len.brown@intel.com Cc: Trammell Hudson <hudson@osresearch.net> Signed-off-by: Andi Kleen <ak@suse.de>
