[PATCH v3 11/16] arm: dts: ls1028a-rdb: sync Ethernet device tree nodes with Linux

In a bit of a blunder, the blamed commit in the Fixes: tag below made
the mscc_felix switch driver look at the 'managed = "in-band-status"'
device tree property, forgetting that the U-Boot device tree had not
been updated to include that property, whereas the Linux one does.

The switch is therefore described in the device tree as not requiring
in-band autoneg, but the PHY driver for VSC8514 (drivers/net/phy/mscc.c)
still enables that feature. This results in a mismatch => no traffic.

This patch is a copy-paste of the Ethernet device tree nodes from Linux,
which resolves that issue. The device tree update also renames the
Ethernet PHY labels.

Fixes: e3789a726269 ("net: dsa: felix: configure the in-band autoneg property based on OF node info")
