x86, olpc: XO-1 uses/depends on PCI

olpc-xo1 uses pci_*() interfaces so it should depend on PCI.

Otherwise we get build failure like:

 arch/x86/kernel/olpc-xo1.c:65: error: implicit declaration of function 'pci_enable_device_io'
 arch/x86/kernel/olpc-xo1.c:71: error: implicit declaration of function 'pci_request_region'
 arch/x86/kernel/olpc-xo1.c:80: error: implicit declaration of function 'pci_release_region'
