Prabhakar Kushwaha a2a55e518f driver/fsl-mc: Add support of MC Flibs
Freescale's Layerscape Management Complex (MC) provide support various
objects like DPRC, DPNI, DPBP and DPIO.
Where:
	DPRC: Place holdes for other MC objectes like DPNI, DPBP, DPIO
	DPBP: Management of buffer pool
	DPIO: Used for used to QBMan portal
	DPNI: Represents standard network interface

These objects are used for DPAA ethernet drivers.
