drivers/intel/gma: Hook up libgfxinit in romstage
A mainboard port needs to: - select `CONFIG_MAINBOARD_HAS_EARLY_LIBGFXINIT' - implement the Ada package `GMA.Mainboard' with a single function `ports' that returns a list of ports to be probed for displays. - set the desired `GFX_GMA_DEFAULT_MMIO' IO memory address to use in romstage (and ramstage) for the graphic device. BUG=b:252792591 BRANCH=firmware-brya-14505.B TEST=libgfxinit compiles in romstage. libgfxinit successfully executes in romstage and ramstage using the requested MMIO setting on skolas.
