Julius Werner 0c5c8f0f80 gru: Add USB 2.0 PHY tuning for Kevin 
This patch sets some magic number in magic undocumented registers that
are rumored to make USB 2.0 signal integrity better on Kevin. I don't
see any difference (unfortunately it doesn't solve the problems with
long cables on my board), but I guess it doesn't hurt either way.

BRANCH=None
BUG=chrome-os-partner:56108,chrome-os-partner:54788
TEST=Booted Kevin with USB connected through Servo. Seems to have
roughly the same failure rate as before.
