x86: pci: Allow configuration before relocation
Add simple PCI access routines for x86 which permit use before relocation. The normal PCI stack is still used, but for pre-relocation use there can only ever be a single hose. After relocation, fall back to the normal access, although even then on x86 machines there is normally only a single PCI bus. Signed-off-by: Simon Glass <sjg@chromium.org>
