mb/foxconn/g41s-k: Add g41m variant

Was tested with the following:
- 2 DIMM slots
- USB
- Ethernet NIC
- automatic fan control
- Libgfxinit with VGA, DVI (HDMI slot unpopulated)
- PS2 Keyboard
- SATA
- PEG
- S3 resume

What does not work:
- Using the second DIMM slot on a channel
  G41 can only handle 2 ranks per channel and on this mainboard 1 rank
  per DIMM slot. Supporting this would require too much raminit rework
  and is not worth it (at least for me)
