Revert "Added Arduino IDE compatible firmware for rev1"

This reverts commit dd7f65f1b69ed02d791ab0e5c61073cac01bbf87.

Main project is now Arduino IDE compatible
working commandline build for Arduino DUE

When using the "native" (not "programming") port, the process is
not as reliable as I would like. When it fails, I find that I
must go through the steps of hard-resetting the board and waiting
until the serial port can be actually used.

Once a flash is successful, and the board is reset, the firmware
works as expected.
