i2c: mxs: change error printing to debug for mxs_i2c_pio_wait_xfer_end
Instead of printing errors after mxs_i2c_pio_wait_xfer_end returns with an error code just print a debug message. NAKs and timeouts can occur in this situation normally, so do not treat them as errors. Signed-off-by: Michael Thalmeier <michael.thalmeier@hale.at> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
