Adding userspace support for the MC (Management Complex) means exporting
an ioctl capable device file representing the root resource container.
This new functionality in the fsl-mc bus driver intends to provide
userspace applications an interface to interact with the MC firmware.
Commands that are composed in userspace are sent to the MC firmware
through the FSL_MC_SEND_MC_COMMAND ioctl. By default the implicit MC
I/O portal is used for this operation, but if the implicit one is busy,
a dynamic portal is allocated and then freed upon execution.
The command received through the ioctl interface is checked against a
known whitelist of accepted MC commands. Commands that attempt a change
in hardware configuration will need CAP_NET_ADMIN, while commands used
in debugging do not need it.

Move the source files out of staging into their final locations:
-mc.h include file in drivers/staging/fsl-mc/include go to include/linux/fsl
-source files in drivers/staging/fsl-mc/bus go to drivers/bus/fsl-mc
-overview.rst, providing an overview of DPAA2, goes to
Documentation/networking/dpaa2/overview.rst
Update or delete other remaining staging files -- Makefile, Kconfig, TODO.
Update dpaa2_eth and dpio staging drivers.
Add integration bits for the documentation build system.
