I2C: Increase priority of i2c_init

Browse Source 
Chipset sometimes needs I2C, therefore i2c_init should have a higher priority
than power_common_init so i2c is available by the time the chipset might be
talking to the battery.

BUG=chrome-os-partner:35502, chrome-os-partner:35173
TEST=There is no "battery not responding" message at startup on veyron
TEST=EC boot takes less than 1 second on veyron
BRANCH=none
