nautilus: Use I2C callbacks to ensure minimum bus free time for battery
Battery on nautilus requires a minimum bus free time of 5ms between
I2C transactions. Use I2C_XFER_CALLBACK mechanism to ensure that this
time is guaranteed before starting a new i2c transaction.
BUG=b:73147310
BRANCH=None
TEST=make -j BOARD=nautilus. Verified on nautilus that no issue is
observed while charging the battery.
