mainboard: Add ASUS P8H61-M LX

Tested with GRUB 2.02 as a payload, booting Debian GNU/Linux 9.5 with
kernel 4.9. This code is based on the output of autoport.

The file `data.vbt` matches the VBT in the latest version of the vendor
firmware (version 4601).

This board works well under coreboot. A list of what works and what
doesn't can be found in the documentation part of this commit. To
summarise: the only known issues are that S3 suspend/resume doesn't
work, and that there is no automatic fan control via the super I/O.
