fs/fs.c: do_fsload: measure throughput
This patch adds time measurement and throughput calculation for all supported load commands. The output of ext2load changes from ---8<--- 1830666 bytes read --->8--- to ---8<--- 1830666 bytes read in 237 ms (7.4 MiB/s) --->8--- Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com> [agust: rebased and revised commit log] Signed-off-by: Anatolij Gustschin <agust@denx.de>
