Subject: [PATCH 0/3] staging: fsl-mc: Move DPBP and DPCON out of staging

Commit 6bd067c48ef ("staging: fsl-mc: Move core bus out of staging")
moves the fsl-mc bus driver infrastructure out of staging to
drivers/bus/fsl-mc. The next step is moving a couple of tightly
connected DPAA2 objects - DPBP (Data Path Buffer Pool) and DPCON
(Data Path Concentrator).

Patch 1 removes dead code from the involved source files.

Patches 2-3 handle moving out the mentioned objects, one at a time.

Some functions and associated structures are not used by current code,
so remove them.
