After booting the u-boot, and first using some SD card (such as Sandisk 2G SD card), because the field 'clock' of struct mmc is zero, this will cause the read transfer is always active and SDHC DATA line is always active, therefore, driver can't handle the next command. Therefore, we use mmc_set_clock to setup both the data structure and HW to the initial clock speed of 400000Hz. Signed-off-by:
