As of now I don't prefer to modify the internal framework as much as 
possible as this is stable DPDK DPAA driver.
There is indeed a planned transition from OF to /sys/ parsing, but it is 
still in pipeline.

You see a blocking issue if we go incremental here?
That would be probably more of replacing this file with another /sys 
parser without much changes to the DPDK glue code.
