lenovo/x230: introduce FHD variant

There is a modification for the x230 which uses the 2nd DP from the dock
as the integrated panel's connection, which allows using a Full HD (FHD)
eDP panel instead of the stock LVDS display.

To make this work with coreboot, the internal LVDS connector should be
disabled in libgfxinit. The VBT has been modified as well, which allows
brightness controls to work out of the box.

The modifications done to the VBT are:
- Remove the LVDS port entry.
- Move the DP-3 (which is the 2nd DP on the dock) entry to the first
  position on the list.
- Set the DP-3 as internally connected.

This has been reported to work with panel LP125WF2 SPB4.
