baytrail: move early init to before mainboard

It's helpful to have a lot of the early init happen
before the handoff to mainboard. One example of this
need is having the BARs programmed so that the mainboard
can read board-specific gpios.

BUG=chrome-os-partner:22865
BRANCH=None
TEST=Built. Booted and saw console outout in bayleybay
     mainboard.
