Gabe Black afca97a29a nyan: big: Set the i2c controller frequencies appropriately.
These had been set to something fairly random which results in a very slow
clock on the bus itself. The new settings take into consideration the speed
the devices on the bus can run at. The TPM can't seem to handle speeds above
40KHz, but some documentation suggests that it should be able to handle up to
at least 100KHz.

BUG=chrome-os-partner:25467
TEST=Built and booted on nyan rev1. Built for big.
BRANCH=None
