boards: add a 'none' machine type to all platforms 



This allows any QEMU binary to be executed with:

  $QEMU_BINARY -M none -qmp stdio

Without errors from missing options that are required by various boards.  This
also provides a mode that we can use in the future to construct machines
entirely through QMP commands.
