src/mb/asrock/g41c-gs: Add variant g41m-s3

This board is pretty much like the G41M-GS, but with DDR3 memory
instead. The PCB layout is almost identical.

What works:
 - S3/S4 resume
 - RAM init
 - Booting to Debian
 - Display lights up w/ libgfxinit
 - Both PS/2 work
 - Ethernet
 - Graphics card on PEG
 - USB
 - SATA ports
 - NVRAM debug_level
 - Internal flashing
 - PCI slots (tested with CT4810 audio card)
 - fancontrol (Only CPU fan can be regulated)
 - Audio (Rear ports only)

What does not work:
 - Hell knows what might be wrong

What is not tested:
 - PCIe x1
 - IDE
 - Floppy
 - Parallel port
