board:samsung: check the boot device and init the right mmc driver.
It is possible to boot device using a micro SD or eMMC slots.
In this situation, boot device should be registered as a block
device 0 in the MMC framework, because CONFIG_SYS_MMC_ENV_DEV
is usually set to "0" in the most config cases.
