Instead of adding the node to the end, can you place it above the
cfgchip node to keep it sorted by reg. We have not really followed that
in this file. May be we should have. But lets start with this.

Can you name the node memory-controller@b0000000? Thats the generic name
suggested by ePAPR 1.1 for memory controllers.

I could not find any naming suggestions for the bus master priority
controller above, but based on the pattern used for other controllers,
may be it should be called priority-controller@14110 instead of mstpri@14110
