So we "fix" some of the problems we see by saying that you can't reset
the board in SPL via DFU.  I think maybe we should instead drop
run_command here and make reset-via-DFU call do_reset() directly like
some other small-size-required cases do.  This will let us drop the
command requirement here but still allow for "use DFU to flash and reset
the board with just SPL" as a use-case.  Thanks!
