Summary

Reading Atmel's AT697E errata document this does not seem like a valid workaround. While the text only mentions SDIV, it says that the ICC flags can be wrong, and those are only generated by SDIVcc. Verification on hardware shows that simply replacing SDIV with SDIVcc does not avoid the bug with negative operands.

This reverts r283727.
