mb/asrock/g41m_vs3_r2: Add mainboard

The following was tested:
- CPUs with 800, 1067, 1333MHz FSB (1333MHz FSB needs a jumper set)
- The VGA output with libgfxinit
- USB
- COM1
- Ethernet
- SATA
- PCIe
- PCI

Has the following problems:
- The Ethernet NIC is not usable after S3 resume and requires Linux to reload
  the driver. Vendor firmware also has this problem so it is quite likely it
  is just a atl1c driver problem.

TODO: Add documentation
