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'
