PPC: Cuda: Use cuda timer to expose tbfreq to guest
Mac OS X calibrates a number of frequencies on bootup based on reading
tb values on bootup and comparing them to via cuda timer values.
The only variable we can really steer well (thanks to KVM) is the cuda
frequency. So let's use that one to fake Mac OS X into believing the
bus frequency is tbfreq * 4. That way Mac OS X will automatically
calculate the correct timebase frequency.
With this patch and the patch set I posted earlier I can successfully
run Mac OS X 10.2, 10.3 and 10.4 guests with -M mac99 on TCG and KVM.

PPC: Add timer handler for newworld mac-io
Mac OS X accesses fancy timer registers inside of the mac-io on bootup.
These really should be ticking at the mac-io bus frequency, but I don't
see anyone upset when we just make them as fast as we want to.
With this patch on top of my previous patch queue and latest OpenBIOS
I am able to boot Mac OS X 10.4 with -M mac99.

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.

The macio code is basically undebuggable as it stands today, with no

Add a DPRINTF macro in the macio source file and add a bunch of debug
prints that are all disabled by default of course.
