Update libgfxinit to the latest master. Changes:
* Remove trailing whitespace in debug output.
* Change some types to make it verify with SPARK Pro.
* Add Broxton (Apollo Lake) support for eDP/DP/HDMI.
* Add Linux user-space test tool `gfx_test`.
* Add a README describing libgfxinit and the build process.
TEST=Booted lenovo/t420 and verified that internal and
external displays are working.

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.

Changes:
o Verification that the framebuffer matches the display mode
o Automatic upscaling if the framebuffer resolution is lower
than the display mode's
o VGA-plane support
o HDMI pixel rate is limited to hardware constraints
o Error tolerant handling of EDID header-pattern

Add `libgfxinit` as another option for native graphics initialization.
For that, the function gma_gfxinit() (see drivers/intel/gma/i915.h) has
to be called by the respective northbridge/soc code.
A mainboard port needs to select `CONFIG_MAINBOARD_HAS_LIBGFXINIT` and
implement the Ada package `GMA.Mainboard` with a single function `ports`
that returns a list of ports to be probed for displays.
v2: Update 3rdparty/libgfxinit to its latest master commit to make
things buildable within coreboot.
v3: Another update to 3rdparty/libgfxinit. Including support to select
the I2C port for VGA.

`libgfxinit` is a SPARK library for graphics modesetting. It supports
Intel integrated graphics only, strictly speaking, the Core i processor
line.
