Hi Grant,

Much needed refinement of mpc5200 device tree binding specifications.

Short list:

- Specify reqiured 'cell-index' property to identify between multiple SOC
  devices of the same type.  (Useful for arbitrating shared register access)

Dale Farnsworth and I have the exact same problem with the Marvell
bridges (e.g., 2 MPSC ctlrs use different bits in the same reg).

Hrm, as I reread this, I may have misunderstood the purpose of cell-index. :(
