intel/lynxpoint,broadwell: Fix eDP display in Windows, SeaBios & Tiano
Without this patch, eDP output is non-functional pre-graphics driver regardless of payload (SeaBIOS, Tianocore) or video init method (VBIOS, GOP driver) and once the standard Windows Intel HD graphics driver is loaded. Test: Boot Windows on peppy and auron_paine, install Intel HD Graphics driver, observe functional eDP output with full video acceleration. Debugging method: adjust location of call to run VBIOS within coreboot, observed that eDP output functional if the VBIOS is run before the power optimizer lines, broken if run afterwards.
