[U-Boot] [PATCH 8/8] mmc: sdhci: change data transfer failure into debug message

[Masahiro Yamada]

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.
