Update: cgd, dk, dm, md, raid, and vnd gracefully detach from the device
tree during shutdown.  I believe that ccd is the only virtual disk that
does not detach.

I have only converted i386 and sparc64 to the new shutdown order.  I
will see about extracting the common code into an MI pre-reboot routine
for the MD cpu_reboot(9) to call.
