DSP: Handle two accelerator loop edge cases properly

There are two special cases that the DSP accelerator handles in a
special way: when the end address is of the form xxxxxxx0 or
xxxxxxx1.

For these two cases, the normal overflow handling doesn't apply.
Instead, the overflow check is different, the ACCOV exception never
fires at all, the predscale register is not updated, reads are not
suspended, and if the end address is 16-byte aligned, the DSP loops
back to start_address + 1 instead of the regular start_address.
