This change replaces printf() with debug() for the notification about commands timeouts.
This is done on purpose (also other drivers use such approach - dw_mmc.c, mvebu_mmc.c), as the mmc core code (mmc.c) uses timeouts to assess if one is using sd card or eMMC device. In such situation timeout is a some kind of a "normal" behavior and there shall not be any output to the console.
There is no impact on boot time for boards using this driver (even in SPL) when two extra timeouts are returned (no SD card present, only eMMC available).
Boot time tested with grabserial: sudo grabserial -b 115200 -d /dev/ttyUSB1 -e 30 -t -m "^U-Boot SPL*"
