mmc: sdhci: change data transfer failure into debug message
During the tuning, drivers repeat data transfer, changing timing
parameters in the controller hardware. So, the tuning commands
(CMD19 for SD, CMD21 for eMMC) fail, and this is not a problem
at all.
Showing "Error detected..." in normal operation just make users
upset. This should not be shown.
