refactor(hw-setup): remove unnecessary includes

[StaticRocket]

Replace these 1 line include files with a TOC tree pointer to the primary file. This can help with switching between distro builds as the path of common files no longer changes.

We currently have 2 different mechanisms to complicate things. One is the TOC tree, the other is arbitrary includes. Modifying the TOC tree is a little hard to parse ahead of time, but it results in a lower likelihood of accidentally creating duplicate content. Using includes results in more files and a deeper file chain you need to parse, but it is clearer ahead of time what is occurring.

I'm in favor of using the TOC tree since that's where a lot of complexity already resides.
