mainboard: Add ASRock H81M-HDS

Tested with GRUB 2.02 as a payload, booting Debian GNU/Linux 9.5 with
kernel 4.9.

This board works quite well under coreboot. A list of what works and
what doesn't can be found in the documentation part of this commit.

The file `data.vbt` matches the VBT in the latest stable version of the
vendor firmware (version 2.20).
