This patch introduces the option to boot from a MMC card parition with
an offset. This can be done by using both defines together:

define CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION 1
define CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR    ((160 << 10) / 512)

The example above loads the main U-Boot at offset 160KiB from the MMC
partition 1.
