Before this fix, the bug would only pop up for addresses that were
dividable by 4. Otherwise, the AMBA AHB 3 Lite widget would return an
error response because of an illegal HSIZE/HADDR combination.
The following tests are now included:
- Check access to registers over AHB bus
- Check access to register over HW interface
- Check access to register over HW interface if hw_wr-input
is disabled.
- Check if the slave responds with a correct error sequence if
an illegal address is accessed.
