drivers/pc80/vga: Add legacy VGA romstage support
This is support for adding legacy VGA support into romstage.
Support for this is being provided by libgfxinit.
The current use case allows us to initialize the display
before memory init (prior to physical memory init) to inform
the user when lengthy memory training is needed.
BUG=b:252792591
BRANCH=firmware-brya-14505.B
TEST=VGA code compiles for romstage
