Merge branch 'DSA-DPAA'

Madalin Bucur says:

====================
adapt DPAA drivers for DSA

Junote Cai reported that he was not able to get a DSA setup involving the
DPAA/FMAN driver to work and narrowed it down to of_find_net_device_by_node()
call in DSA setup. The initial attempt to fix this by adding of_node to the
platform device results in a second, failed, probing of the FMan MAC driver
against the new platform device created for the DPAA Ethernet driver.
Solve these issues by removing the of_node pointer from the platform device
and changing the net_dev dev to the of_device dev to ensure the DSA init
will be able to find the DPAA net_dev using of_find_net_device_by_node().
Several changes were required to enable this solution: refactoring the
adjust_link (also resulted in lesser, cleaner code) and renaming the fman
kernel modules to keep the legacy udev rules happy.

Changes in v2:

 - fix issue on error path in "dpaa_eth: change device used" patch
 - cleanup the dpaa_eth_probe() error paths

Changes in v3:

 - remove obsolete comment in moved code
 - add explanation for module rename
