commit 38af36132ede27a1abc5542c81453a9d9fde7fe5

    rambi: align gpu pipea settings with the VBIOS
    
    In the normal mode case these settings aren't overwritten by
    the VBIOS because the VBIOS does not run. Therefore, the settings
    need to align with what the VBIOS programs so that there is a
    consistent panel power sequencing.
    
    BUG=chrome-os-partner:28267
    BRANCH=baytrail
    TEST=Built and booted. Noted settings set by firmware for both dev
         and normal mode match.
