AMD: Drop empty root_complex

There are no files to build left under AMD nortbridge/x/root_complex
    directories. For some cases, even the Kconfig file was no longer sourced.
    Remove all such references and empty files.

For devicetree.cb treat component paths with "/root_complex" in them valid
    even when the directory does not exists. This is because AMD boards us this
    dummy chip component as the root node in their devicetree.cb.

The generated devicetree file static.c remains unchanged.
