staging: fsl-mc: Move DPCON out of staging
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 Signed-off-by: Bogdan Purcareata <bogdan.purcareata@nxp.com> Reviewed-by: Laurentiu Tudor <laurentiu.tudor@nxp.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
