3rdparty/libgfxinit: Update submodule pointer

Some renamings force us to update our code:

  * Scan_Ports() moved into a new package Display_Probing.

  * Ports Digital[123] are called HDMI[123] now (finally!).

  * `Configs_Type` became `Pipe_Configs`, `Config_Index` `Pipe_Index`.

Other noteworthy changes in libgfxinit:

  * libgfxinit now knows about ports that share pins (e.g. HDMI1 and
    DP1) and refuses to enable any of them if both are connected
    (which is physically possible on certain ThinkPad docks).

  * Major refactoring of the high-level GMA code.
