This is the first step towards getting rid of the kludge which is VirtFdtDxe.
This series addresses the cases where other DXE drivers rely on dynamic PCDs populated by VirtFdtDxe, which requires it to execute first using an A PRIORI declaration. Instead, this series moves the DT node parsing to the respective users, using a new FDT client protocol which can be used in the various depexes. The next step is to split the remaining handling performed by VirtFdtDxe into drivers appropriate for the platforms, i.e., virtio for QEMU and xeniommio for Xen domU. This is somewhat rough around the edges, but is mostly intended to elicit discussion, and I fully expect these changes to make it into the tree looking a lot different from this v1.
