mainboard: Add Supermicro X10SLM+-F

This board runs well with coreboot. The documentation part of this
commit lists what works and what doesn't.

Tested with GRUB 2.02 as a payload, loading SeaBIOS 1.12.0 which then
boots FreeBSD 11.2. It has also been tested with GRUB directly booting
Debian GNU/Linux 9.6 (kernel 4.9).
