Decoding a processor number on a UE10000

example: /SUNW,UltraSPARC@1f,0

/SUNW,UltraSPARC@1f,0 = system 7, proc 3



		1		f
           ----------      -----------
           00       01     11       11
            -       ---------       --
            A         B              C



A =>  1 = IO or 0 = proc

B =>  system board number 0-f

C =>  proc number 0-3
