gigabyte/ga-b75m-d3h: Add new Intel mainboard

This is based on LENOVO X230 port.
Board boots to linux via SATA or USB.
All USB ports are working.

Remaining Issues:

1. Native raminit sometimes fails with "timC write discovery failed"
   even without changing the ram configuration. I suggest
   altering the native raminit code so that it reboots
   if that message appears to give a chance for the
   boot process to recover.

2. VGA does not work.
   Native graphics initialization only supports LVDS and
   the VGA Option ROM still hangs when run in SeaBIOS.
