mb/asrock: Add ASRock H77 Pro4-M mainboard

This adds a new port for the ASRock H77 Pro4-M motherboard. It is
microATX-sized with an LGA1155 socket and four DIMM sockets for DDR3
SDRAM.

The port was initially done with autoport. It is quite similar to the
ASRock B75 Pro3-M which is already supported by coreboot.

Working:
- Sandy Bridge and Ivy Bridge CPUs (tested: i5-2500, Pentium G2120)
- Native RAM initialization with four DIMMs of two different types
- PS/2 combined port (mouse or keyboard)
- Integrated GPU by libgfxinit on all monitor ports (DVI-D, HDMI, D-Sub)
- PCIe graphics in the PEG slot
- All three additional PCIe slots
- All rear and internal USB2 ports
- All rear and internal USB3 ports with reasonable transfer rates
- All six SATA ports from the PCH (two 6 Gb/s, four 3 Gb/s)
- All two SATA ports from the ASM1061 PCIe-to-SATA bridge (6 Gb/s)
- Rear eSATA connector (multiplexed with one ASM1061 port)
- Console output on the serial port of the Super I/O
- SeaBIOS 1.15.0 to boot slackware64
- SeaBIOS 1.15.0 to boot Windows 10 (needs VGA BIOS)
- Internal flashing with flashrom-1.2 (needs `--ifd -i bios --noverify-all`)
- External flashing with flashrom-1.2 and a Raspberry Pi 1
- S3 suspend/resume from either Linux or Windows 10

Not working:
- Booting from the two SATA ports provided by the ASM1061
- Automatic fan control with the NCT6776D Super I/O

Untested:
- VBT (it is included, though)
- Infrared header
