spl: MMC U-Boot image load from raw partition
Raw images of U-Boot can be stored inside MMC partitions, so it makes sense to
read the partition table, looking for a partition number instead of using
a fixed sector address.

[trini: Only add mmc_load_image_raw_partition() when
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION to avoid warning, add missing
conversion in spl_mmc_load_image()]
