mb/lenovo/x230: Enable libgfxinit

Tested on X230 with an external screen connected to every one of the
DP ports (miniDP on mainboard, two DP ports on dock), the GRUB payload
can display on both the external screen and the internal LVDS screen.

This is a copy-paste of I8e02c8003ff745d05ee272c59377174847f5219c.
