Hello Bora Guvendik, Hannah Williams, Anil Kumar K, Cliff Huang, Paul Menzel, Angel Pons, Arthur Heymans, Zhixing Ma, Tarun Tuli, Nico Huber, Michał Żygowski, Subrata Banik, Nick Vaccaro,

I'd like you to reexamine a change. Please visit

cpu/intel/car/romstage: Clear graphics before exiting romstage

Leaving the graphics configuration with the display on confuses the
FSP GOP driver and can lead to undesired graphics artifacts.

This CL introduces the GRAPHICS_OFF_BEFORE_RAMSTAGE configuration flag
to trigger graphic off procedure.
