PPC: dbdma: Allow new commands in RUN state

The DBDMA controller can not change its command stream while it's
actively streaming data, true. But the fact that it's in RUN state
doesn't actually indicate anything. It could just as well be in
WAIT while in RUN. And then it's legal to change commands.

This fixes a real world issue I've encountered with Mac OS X.
