Add a uclass for PCI controllers and a generic one for PCI devices. Adjust the 'pci' command and the existing PCI support to work with this new uclass. Keep most of the compatibility code in a separate file so that it can be removed one day. TODO: Add more header file comments to the new parts of pci.h Signed-off-by: Simon Glass <sjg@chromium.org>
