3rdparty/libgfxinit: Update submodule pointer

Update libgfxinit to current master. Changes include:

* a fix to decode the size stolen memory correctly on pre-SandyBridge
  hardware,
* a PCI id based generation check, obsoleting the old check based
  on PCH audio ids,
* some minor improvements around rarely used DDI ports (D and E), and
* added support for tiled and rotated framebuffers on Skylake+ hardware
  (less interesting for coreboot, I guess?).
