ENGR00315499-19 Fix eMMC fast boot hang issue
When booting in eMMC fast boot, the uboot v2013.04 always hangs.
The root cause is that MMC host does not exit from boot mode after
bootrom loading image. So the first command 'CMD0' sent
in uboot will pull down the CMD line to low and cause errors.
This patch cleans the MMC boot register in "mmc_init" to put the
MMC host back to normal mode.
