I was able to use this code to find the lmu-controller node and read
the address from 'reg' - looks like it's the value shifted right one
bit.  (An old posting[1] does it similarly.)  But I can't work out how
to get the bus number (probed as 8 on my machine).  The linked patch
tries to use the last bit of 'reg', but that can't be right.
