Add a dm_ prefix to driver model I2C functions so that we can keep the old ones around. This is a little unfortunate, but on reflection it is too difficult to change the API. We can undo this rename when most boards and drivers are converted to use driver model for I2C. Signed-off-by: Simon Glass <sjg@chromium.org>
