add DM/DTS support for the UEC ethernet on QUICC Engine
Block.
Signed-off-by: Heiko Schocher <hs@denx.de>
Patch-cc: Mario Six <mario.six@gdsys.cc>
Patch-cc: Qiang Zhao <qiang.zhao@nxp.com>

Series-changes: 3
- revert:
commit "3374264df97b" ("drivers: net: qe: deselect QE when DM_ETH is enabled")
as now qe works with DM and DM_ETH support.
- fix mailaddress from Holger
Series-changes: 2
- add comments from Qiang Zhao:
- add device node documentation
- I did not drop the dm_qe_uec_phy.c and use drivers/net/fsl_mdio.c
because using drivers/net/fsl_mdio.c leads in none existent
udevice mdio@3320
instead boards with DM ETH support should use now this
driver.
- remove RFC tag
Commit-notes:
- I let the old none DM based implementation in code
so boards should work with old implementation.
This Code should be removed if all boards are converted
to DM/DTS.
- add the DM based qe uec driver under drivers/net/qe
- Therefore copied the files uccf.c uccf.h uec.h from
drivers/qe. So there are a lot of Codingstyle problems
currently. I fix them in next version if this RFC
patch is OK or it needs some changes.
- The dm based driver code is now under drivers/net/qe/dm_qe_uec.c
Used a lot of functions from drivers/qe/uec.c
- seperated the PHY specific code into seperate file
drivers/net/qe/dm_qe_uec_phy.c
