arc: re-generate defconfigs

Before that moment our defconfigs were manually modified with addition
of new options. That means once anybody wants to add another option and
re-genarate defconfig with "make defconfig" there will be lots of
differences. So to make future modifications more clean we'll do bulk
re-generation right away.
