If U-Boot is located on MMC, SPL and U-Boot proper are glued together.
More precisely, SPL is stored 4 times. Take this and its padding into
account and adjust sector number via board_spl_mmc_get_uboot_raw_sector.
This allows loading from a partition, without the need to hard-code the
offset via SYS_MMCSD_RAW_MODE_U_BOOT_USE_SECTOR

Please add a comment whether this is offset within a partition or within
a raw block device.
Also, I see the long discussion thread, maybe it would be good to point
out which commit exactly broken the DE0 board.
