Add a nasty hack to get remote kernel gdb working from ddb. ddb would
complain before that a suitable gdb port had not been setup because gdbdev
was NULL. This abuses the fact that the gdb port is hard-coded to the
address normally assigned to sio1 and thus hard-codes in sio1 as the gdb
port. Yuck.
