Patch Set 1:
> If the values are generated from vbt, would it be possible to generate them at runtime if a vbt.bin is present ? That way you just add the right VBT and it works out of the box.

Technically, that's doable. But you'd have to maintain
VBTs with the correct settings. I just assumed here that
these cros devices have the correct settings in their VBT
because Linux' i915 would use these values (in theory).
But is that generally true? and who is going to write the
tool to configure VBT?

Also, our devicetrees are full of values that we could
pre-configure in FSP binaries. We don't do that either.
