mainboard: Add MSI MS-7788

NOTES:
* This is the product of a beginner running `autoport`
  please forgive any gaps in my knowledge about the project
* There are still some ugly hacks in this commit that I would
  like to test and eventually fix
* I still probably need to properly fill in documentation
* I also probably should understand everything in this commit!
  (not just let autoport to the heavy lifting)
* And I need to look over the `FIXME`s

* MSI h61m-p31/w8
* Winbond 25Q64FVSIG
* Fintek F71868AD

Working:
* PCIe graphics
* Integrated graphics
* USB (all ports)
* Ethernet

Yet-to-be-thoroughly-tested:
* All SATA ports
* All PCIe ports (as in the x1 lane)
* Super/IO (is my chip supported?)
* Suspend states
* Integrated graphics (libgfxinit)
* ME (and neutering it?)

Untested:
* PS/2
