This patchseries introduce simple PCI bus support for barebox.
Changes since RFC v3:
* rebase over latest 'next';
* use list for pci_root_buses;
* move common PCI Kconfig stuff from arch/mips to drivers/pci;
* make pci_*_write_config_* PCIe-friendly (use 'int' type for
config register address);
* drop some unused stuff;
* change lspci "no pci" error message to "No PCI bus detected";
* rtl8139: use dma_alloc_coherent();
* rtl8139: use pci_set_master() & pci_clear_master().
TODOs for RFC v3:
* no PCI bridges support;
* introduce pci_resource_start();
* introduce pci_iomap();
* clean '#if 0'.
