The dfu_alt_info_spl variable allows passing a starting point for the binary to be flashed in the SPI NOR.
For example, if we have 'dfu_alt_info_spl=spl raw 0x400', this means that we want to flash the binary starting at address 0x400.
In order to do so we need to erase the entire sector and write to the the subsequent SPI NOR sectors taking such start address into account for the address calculations.
Tested by succesfully writing SPL binary into 0x400 offset and the u-boot.img at offset 64 kiB of a SPL NOR.

After making this use lldiv() for the math, Applied to u-boot/master, thanks!
