i2c: Make i2c_xfer a wrapper function to chip_i2c_xfer
i2c_xfer was previously implemented at the chip-level, but now we want
to add some global retry logic. Rename the chip-level i2c_xfer functions
to chip_i2c_xfer and add a new global wrapper function i2c_xfer.
BUG=chrome-os-partner:39613
TEST=Run "battery" from EC console on Cyan, verify that values + strings
are correctly printed.
