====================
dpaa2-eth: Move DPAA2 Ethernet driver

The Freescale/NXP DPAA2 Ethernet driver was first included in
drivers/staging, due to its dependencies on two components located
there at the time of its initial submission:
* the fsl-mc bus driver, which was moved to drivers/bus in kernel 4.17
* the dpio driver, which was moved to drivers/soc/fsl in kernel 4.18

More information on the DPAA2 architecture and the interactions
between the fsl-mc bus and the objects present on it can be found in:
Documentation/networking/dpaa2/overview.rst

For easier review, the patch is generated without the -M option,
although the driver files are moved without any code changes.

changes since v1[1]:
* remove RFC label, since dependencies have been merged on net-next
* add patch fixing a possible race at probe (reported by Andrew Lunn)
