mpc83xx, keymile boards: enable DM_ETH and add DTS

enable DTS support for keymile mpc83xx based boards.

get rid of compile warning:
===================== WARNING ======================
This board does not use CONFIG_DM_ETH (Driver Model
for Ethernet drivers). Please update the board to use
CONFIG_DM_ETH before the v2020.07 release. Failure to
update by the deadline may result in board removal.
See doc/driver-model/migration.rst for more info.
====================================================

Therefore done:
- add DTS for all mpc83xx based boards from keymile
  mainly they are not mainlined to linux.
- add u-boot specific dtsi
- add stdout-path
- add missing ucc4 par_io definitions, which were
  in board code, but not in linux DTS
- remove not used ethernet nodes

Series-changes: 2
- add patch which fixes Codingstyle errors in drivers/qe
- add patch which converts the mpc83xx based boards from
  keymile to DM_ETH

Cover-letter:
powerpc, mpc83xx: add DM_ETH support

This patch series adds DM ethernet support for mpc83xx based
keymile boards.
