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.
