[PATCH v2] board: sl28: add DSA support for variant 2

[Michael Walle <michael@walle.cc>]

Now that u-boot gained DSA support, and it is already enabled for the
kontron_sl28 board, add the last missing piece and enable the
corresponding devices it in the device tree.

changes since v1:
 - renamed ethernet alias stem, because it was changed in
   commit 82a3c9ef20d43d97416589854b4bbcb4c2450c24 ("net: use the same
   alias stem for ethernet as linux")

Now that the mentioned commit made it finally into u-boot. We can move
forward here. It would be nice if this would still make it into 2021.07,
given that this is only a device tree change for a this particular board.
