[RFC V2 0/6] barebox PCI support

[Antony Pavlov]

This patch series introduce PCI support to barebox.

Thanks to Jean-Christophe PLAGNIOL-VILLARD for reviewing and adding
some PCI common code.

The patches are draft. They need a very big future work, so I put on them "RFC"
title instead of "PATCH".
