The command "time" shows the execution time of the command given
to the argument, like this:
time: 45.293 seconds, 45293 ticks
Since we adopted CONFIG_SYS_HZ = 1000 for all boards,
we always have a simple formula: "1 tick = 0.0001 second".
Showing ticks looks almost redundant.

As far as every arch has a get_timer function,
run_command_and_time_it code can now disappear.

Change all files in common/ to use CMD_RET_USAGE instead of calling
cmd_usage() directly. I'm not completely sure about this patch since
the code since impact is small (100 byte or so on ARM) and it might
need splitting into smaller patches. But for now here it is.
