3rdparty/lib{hwbase,gfxinit}: Update to latest master
Simplifies our C interface function gma_gfxinit(), due to the following
changes:
* *libgfxinit* knows about the underlying PCI device now and can
probe MMIO addresses by itself.
* The framebuffer mapping is now completely handled inside the
library where we validate that we neither overflow
- the stolen memory,
- the GTT address space, the GTT itself nor
- the aperture window (i.e. resource2 of the PCI device)
that we use to access the framebuffer.
Other changes:
* Fixes and a quirk for DP training.
* Fix for DP-VGA adapters that report an analog display in EDID.
* Fixes for Skylake support with coreboot.
* DDI Buffer drive-strength configuration for Haswell, Broadwell and
Skylake.
* `gfx_test` can now be run from X windows (with glitches).
* Compatibility with GCC 7 and SPARK GPL 2017.
TEST=Booted lenovo/t420 and verified that everything works as usual.
