Some I2C bus implementations need to synchronize with external entities, such as system firmware, which might also be programming the same I2C bus. In order to facilitate this add ->xfer_begin() and ->xfer_end() hooks which are invoked around pcf_xfer(). [JD: Make these hooks optional.] Signed-off-by: David S.
