spl: spl_mmc: provide one weak function spl_boot_partition

The spl_boot_partition function has been added in order to have
the possibility to boot on a same binary from different mmc devices
with different partitions.

By default keep the current behavior, SPL use the partition defined
by CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION.
