mb/siemens/chili: Add new mainboard
The Chili base board is a ruggedized laptop with additional industrial
interfaces. So far, only booting and basic interfaces (USB, UART,
Video) are working with the original model, the "base" variant.
No further development is planned for this variant, as our primary
target was another one that will be added in a follow-up.
