staging: fsl-mc: Added Freescale Management Complex APIs

APIs to access the Management Complex (MC) hardware
module of Freescale LS2 SoCs. This patch includes
APIs to check the MC firmware version and to manipulate
DPRC objects in the MC.

+* Add README file (with ASCII art) describing relationships between
+  DPAA2 objects and how combine them to make a NIC, an LS2 switch, etc.
+  Also, define all acronyms used.
+
+* Decide if multiple root fsl-mc buses will be supported per Linux instance,
+  and if so add support for this.
+
+* Add at least one device driver for a DPAA2 object (child device of the
+  fsl-mc bus).
+
+Please send any patches to Greg Kroah-Hartman <greg@kroah.com>,
