mainboard/lenovo: add Lenovo Z61t laptop

This platform shares most hardware components with first-gen Core
Lenovo laptops such as T60/X60, with much smaller EEPROM size as
one of notable differences. The port features Intel graphics,
ATI-based version should work with vendor VBIOS.

Tested peripherals:
 - sleep/resume,
 - USB ports,
 - ACPI Fn key bindings/volume buttons,
 - backlight control,
 - ethernet,
 - wireless (under Linux),
 - sound/beep,
 - dock handling,
 - serial via dock.

Untested peripherals:
 - IrDA,
 - parallel port,
 - PCMCIA,
 - S-Video port,
 - modem,
 - FP reader (should just work),
 - IEEE1394.

Linux 3.16 works with native gfxinit perfectly, with Intel VBIOS
console sometimes displays nothing when i915 framebuffer is used.

Windows 7 has an interrupt assignment issue with iw3945, otherwise
tested stuff is fine.
