atmel-samd: Support auto-reset based on USB write activity.

It will soft-reboot micropython after a burst of writes to the
file system. This means that after you save files on your computer
they will be automatically rerun.

This can be disabled in the build by unsetting AUTORESET_TIMER in
mpconfigboard.h.

Using the REPL will also prevent the soft resets until you reset
with CTRL-D manually.
