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
