mb/gigabyte/ga-h61m-s2pv: Add new mainboard

Tested with GRUB 2.02 as a payload, booting Arch Linux with
latest kernel. This code is based on the output of autoport
as well as existing ga-b75m-d3h and ga-b75m-d3v mainboards.

Working:
 - Serial port I/O
 - S3 suspend/resume (broken with SeaBIOS 1.11.1)
 - USB ports and headers
 - Gigabit Ethernet
 - Integrated graphics (libgfxinit)
 - PCIe x16 graphics
 - PCIe x1
 - SATA controller
 - Hardware Monitor
 - Fan Control (fancontrol on linux works well)
 - Native raminit (4+4GB, 4+2GB, 2+2GB, DDR3-1333)
 - Native graphics init with libgfxinit
 - flashrom, using the internal programmer. Tested with coreboot,
   as well as with the vendor firmware. Backup chip is untested.
 - NVRAM settings. Only `gfx_uma_size` and `debug_level` have been
   tested with values different from the default.

Untested:
 - VGA BIOS for integrated graphics init
 - DVI port. It can detect a "fake" display, that is, an
   EEPROM connected to the DVI port.
 - PS/2 ports
 - Audio: Only rear output (green) has been tested.
 - EHCI debug.
 - Parallel port
 - Non-Linux OSes
 - ACPI thermal zone and fan control (probably not working)

Not working:
 - SATA devices with Tianocore (payload issue)
 - PCIe to PCI bridge. It seems to be poorly supported on Linux,
   it lacks a public datasheet and vendor BIOS behaves in the
   same way: The bridge and the devices behind it appear, but
   drivers fail to find devices attached to the bridge.
