3rdparty/libgfxinit: Update submodule pointer
This includes a huge set of refactorings to support Core Display Clock (CDClk) frequency switching based on the current mode requirements. The CDClk is configurable since Haswell and runtime switching is suppor- ted since Broadwell. Always using the lowest possible frequency setting should allow some power-savings. While, on the upper end, we can support higher resolution panels now, without having to change the static confi- guration. There have also been some smaller changes and fixes, including: o Parsing of eDP 1.4+ DPCD link rates, enables panels that don't advertise a maximum link rate but only individual ones. o DP support for Ibex Peak. o Corrected limit for HDMI on G45 to 165MHz. o Reworked GMBUS reset handling and timeouts, should help with stalled GMBUS controllers when unimplemented ports were probed by accident. Tested on various boards from GM45 to KBL-R.
