commit ba556197cbc80dc413a4bcda281a065f1b7417c8
Author: Edward O'Callaghan 
Date:   Sun Mar 16 17:24:18 2014 +1100

mainboard/lenovo: [2/2] implement initial T530 support

Step 2: change the Lenovo X230 code to adapt it to the new board's
    hardware with the great guidance from Vladimir (phcoder) to find the
    correct GPIO's.

The machine has:
     - Chipset: Intel QM77
     - GPU's: Intel Integrated HD Graphics
            : Discrete NVIDIA NVS 5400M (1 GB VRAM) with Optimus Technology
