arm: socfpga: improve raw MMC SPL boot
Before this patch, when booting from MMC (no filesystem), the SPL loaded U-Boot from a fixed offset. It will now load U-Boot from an offset of 256kB (which is 4 times the padded SPL image) in the third partition. This behaviour is similar to what the vendor SPL (based on U-Boot 2013.01) does, and allows to directly 'dd' the u-boot-with-spl.sfp file to the A2 partition.
