snow: Enable I2C bus arbitration on host port
Enable this feature so that we can be a bus master on the I2C host
port when the AP is not using it.
BUG=chrome-os-partner:10888
TEST=manual:
build for all boards
boot on snow, test that:
- keyboard still works in U-Boot
- battery charging is enabled
- U-Boot can see TPSCHROME
- keyboard works in kernel
- kernel reports battery levels correctly
