mb/asus/p8z77-v_lx2: Add new mainboard

This is an ATX mainboard with a LGA1155 socket and four DDR3 DIMM slots.
Porting was done using autoport and then doing a bunch of manual edits.

Working:
 - All four DIMM slots
 - Serial port to emit spam
 - PS/2 keyboard
 - S3 suspend/resume
 - Rear USB ports
 - Integrated graphics (libgfxinit)
 - HDMI and VGA
 - All PCIe ports
 - Realtek GbE (coreboot must set the MAC address)
 - Both PCI ports behind the ASM1083 PCI bridge
 - SATA ports
 - Native raminit
 - Flashing with flashrom
 - Rear audio output
 - VBT
 - SeaBIOS to boot Arch Linux

Untested:
 - PS/2 mouse
 - The other audio jacks
 - EHCI debug
 - Front USB headers
 - Non-Linux OSes
