change to of MTD partition parsing

[Kumar Gala]

Ben,

The following commit breaks the previous definition of flash  
partitions according to Documentation/powerpc/dts-bindings/mtd- 
physmap.txt.  Using the 'name' field is bad practice.  What was going  
on w/the SLOF case?

     [MTD] ofpart: Check name property to determine partition nodes.

     SLOF has a further node which could not be evaluated
     by the current routine. The current routine returns
     because the node hasn't the required reg property. As
     fix this patch adds a check to determine the partition
     child nodes. If the node is not a partition the number
     of total partitions will be decreased and loop continues
     with the next nodes.
