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.

As discussed previously, this change relies on a tiny sprintf()
implementation to be provided to be able to build and boot correctly.
Also, I removed CONFIG_SYS_U_BOOT_MAX_SIZE_SECTORS, but I plan to
send a patch removing this obsolete define from all the configs,
so there might be a merge conflict, sorry...
I completely missed a previous occurrence of this problem
(http://lists.denx.de/pipermail/u-boot/2016-May/254492.html), so I'm
adding the previous reporter as Cc.
