We need some sort of mapping between a message register and a message

some sort of API (e.g. 'mpic_msgr_read(0)').  One way to do that would 
be by putting an order on the registers.  Maybe there is a better way, 
though ...

A message register is uniquely identified by a reference to the device
tree node, plus a 0-3 index into that node's message registers.
