net: Remove extraneous dependencies

With DM_ETH being required now for all drivers, we don't need this
listed on individual drivers as well.

net, qe: add DM support for QE UEC ethernet

add DM/DTS support for the UEC ethernet on QUICC Engine
Block.

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
