[PATCH] Remove suspend() calls from shutdown path 

This removes the calls to device_suspend() from the shutdown path that
were added sometime during 2.6.13-rc*.  They aren't working properly on
a number of configs (I got reports from both ppc powerbook users and x86
users) causing the system to not shutdown anymore.

I think it isn't the right approach at the moment anyway.  We have
already a shutdown() callback for the drivers that actually care about
shutdown and the suspend() code isn't yet in a good enough shape to be
so much generalized.  Also, the semantics of suspend and shutdown are
slightly different on a number of setups and the way this was patched in
provides little way for drivers to cleanly differenciate.  It should
have been at least a different message.

For 2.6.13, I think we should revert to 2.6.12 behaviour and have a
working suspend back.
