dw_mmc: Print error message on error.
During a board bringup we observed random hangs in SPL,
which turned out to be caused by communication errors with
an SD card. However, the driver did not say a single character
and neither did the upper layers.
This patch changes the driver to print a short but precise
error message if there is a communication problem with
the SD card.
