fs: fat: fix fatwrite overflow calculation

The overflow calculation was incorrect. Adding the start block of the
partition is not needed because the sectors are already relative to the
beginning of the partition. If you attempted to write a file smaller
than cur_part_info.start blocks on a full partition the old calculation
fails to catch the overflow. This would cause an infinite loop in the
determine_fatent function.

Old, incorrect calculation:

ending sector of new file = start sector + file size (in sectors)
last sector = partition start + total sectors on the partition

Adding the partition start block number is not needed because sectors
are already relative to the start of the partition.

New calculation:

arch/sh: allow building in big-endian mode

endian mode. Some SuperH SoCs get the little vs. big endian decision
through mode pins sampled at reset, so if big endian has been choosen
by HW designers, it cannot be easily changed.

Therefore, it makes sense to allow building U-Boot for SuperH in big

OUTPUT_FORMAT() in the linker script.
