mainboard: Add ASRock G41C-GS

Start-point is Gigabyte GA-G41M-ES2L.

This board features a G41 northbridge and an ICH7 southbridge. This
board has slots for both DDR2 and DDR3 (cannot run concurrently
though) but only DDR2 is implemented in coreboot. The SPI flash
resides in a DIP-8 socket.

Tested and working:
* DDR2 dual channel (PC2 5300 and PC2 6400, though raminit is picky
  with assymetric dimm setups);
* 3,5" IDE;
* SATA;
* PCIe x16 (with some patches up for review);
* Uart, PS2 Keyboard;
* USB, ethernet, audio;
* Native graphic init;
* Fan control;
* Reboot, poweroff, S3 resume;
* Flashrom (vendor and coreboot).

Tested but fails:
* DDR3 (not implemented in coreboot).

Tests were run with SeaBIOS and Debian sid, using Linux 4.9.0.
