drivers/intel/gma: Hook up libgfxinit
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.
