mb/asrock: Add Z87M OC Formula (Haswell)main

This port was done via autoport and subsequent manual tweaking.
Special thanks to Nicholas Chin! This port would have never succeeded
without his help.

The board features two socketed DIP-8 SPI flash chips, as well as a
BIOS selection switch and onboard Power and Reset switches.

Working:
- Haswell MRC.bin
- All four DDR3/DDR3L DIMM slots
- S3 suspend and resume
- Libgfxinit
- HDMI-Out Port
- USB 2.0 Ports
- Vertical Type A USB 2.0
- USB 3.1 Gen1 Ports
- HD Audio Jack (audio output)
- Front panel audio connector (audio output)
- RJ-45 Gigabit LAN Port
- SATA3 6.0 Gb/s connectors
- mSATA/mini-PCI Express slot
- half mini-PCI Express slot
- PCI Express 3.0 x16 slots (both)
- PCI Express 2.0 x4 slot
- PCI Express 2.0 x1 slot

Working (board-specific)
- Power Switch with LED (functional, yet no LED)
- Reset Switch with LED (functional, yet no LED)
- BIOS Selection Switch
- Slow Mode Switch (locks the CPU at 800MHz)

not (yet) tested:
- IR header
- COM Port header
- Power LED header
- eSATA connector
- USB 2.0 headers
- PS/2 Mouse/Keyboard Port
- HDMI-In Port
- Optical SPDIF Out Port

not (yet) working:
- Software fan control: While the Nuvoton chip is correctly discovered,
the numbering of the fan connectors is faulty, resulting in the wrong
fan being controlled.
- Dr. Debug: on vendor firmware, the LEDs turn off after successful
boot. On coreboot, the LED shows two bright zeros after boot.
- Post Status Checker (PSC)
