hw/m68k/mcf5206: Replace remaining hw_error()s by qemu_log_mask()
hw_error() dumps the CPU state and exits QEMU. This is ok during initial code development (to see where the guest code is currently executing), but it is certainly not the desired behavior that we want to present to normal users, and it can also cause trouble when e.g. fuzzing devices. Thus let's replace these hw_error()s by qemu_log_mask()s instead.
