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.
