soc/intel/common/block/early_graphics: Introduce a 200 ms delay
It has been reported that the PEIM graphics driver may temporarily
fail communication with the display if the time between libgfxinit
turning off the displays and the PEIM driver initialization is too
short. 200 ms has been identified as a safe delay.
This is a temporary workaround and an investigation is in progress to
come up with a better and long term solution.
