The open/reset/close commands format is similar for all objects.
Currently there are multiple implementations for these commands
scattered through various drivers. The code is cavsi-identical.
Create a generic implementation for the open/reset/close commands.
One of the consumer will be the VFIO driver which needs to
be able to reset a device.

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:
- dpcon.c goes to drivers/bus/fsl-mc/, next to the core infrastructure
- dpcon-cmd.h gets merged into drivers/bus/fsl-mc/fsl-mc-private.h, next
to the other internally used APIs
- dpcon.h gets merged into include/linux/fsl/mc.h, exposing the public
API
Update references in the dpaa2-eth staging driver.
DPCON stands for Data Path Concentrator - an interface between DPIO
(Data Path IO) and its users (e.g. dpaa2-eth). You can read more about
DPIO in Documentation/networking/dpaa2/overview.rst

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.
