For now most platforms support display function at PEI phase. But the conspliter and graphics console driver would clear the screen at BDS connect console phase. Maybe some platforms would show logo in the next or maybe not. For consumers, it looks like the screen flashed. So change the behavior of graphics console devices while connect console devices to maintain seamless screen from PEI.
Test has done on MinPlatform Kabylake-RVP3 which support PEI display.
