x86: Add a minimal example SoC along with a board
The min86 example SoC code along with the example mainboard
should serve as a minimal example how a buildable x86 SoC code
base can look like.
This can serve, for instance, as a basis to add new SoCs to
coreboot. Starting with a buildable commit should help with
the review of the actual code, and also avoid any regressions
when common coreboot code changes.
As the example code itself is build-tested, it should advance
with coreboot and can't rot like documentation might. It also
serves as a check what APIs need to be implemented with the
default Kconfig settings.
