staging: fsl-mc: Move DPBP out of staging
Move the source files out of staging into their final locations: - dpbp.c goes to drivers/bus/fsl-mc/, next to the core infrastructure - dpbp-cmd.h gets merged into drivers/bus/fsl-mc/fsl-mc-private.h, next to the other internally used APIs - dpbp.h gets merged into include/linux/fsl/mc.h, exposing the public API Update references in the dpaa2-eth staging driver. DPBP stands for Data Path Buffer Pool - you can read more about the object 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>
