broadwell: Only do pre-graphics delay when running option rom

This changes the broadwell graphics init path to only do the delay
    before initializing graphics when running chromeos if we are also
    going to execute the option rom.

BUG=chrome-os-partner:33671
    BRANCH=samus
    TEST=build and boot on samus
