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
- Rear USB3 ports with reasonable transfer rates
- Internal USB3 header (2 ports)
- All six SATA ports from the PCH
- All two SATA ports from the ASM1061 PCIe-to-SATA bridge
- Console output on the serial port of the Super I/O
- SeaBIOS 1.14.0 to boot slackware64
- SeaBIOS 1.14.0 to boot Windows 10 (needs VGA BIOS)
- 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
- Fan control with the NCT6776D Super I/O
- Internal flashing with flashrom-1.2 (no write permission on BIOS
  region).

Untested:
- VBT (it is included, though)
- SATA 6Gb/s
- Rear eSATA connector
- Infrared header
