target/cris/translate: Get rid of qemu_log_separate()

The gen_BUG() function calls already cpu_abort(), which prints the
information to stderr and the log already. So instead of additionally
printing the dc->pc via fprintf() and qemu_log here, too, we can
simply pass this information to cpu_abort() instead.
