Upstream commit 6d4cd04 changes how the internal delays of the AR803x
based PHYs are enabled. With this commit, all internal delays are
disabled on driver probe and enabled based on the 'phy-mode' property in
the device-tree.
Before this commit, the RX delay was always enabled upon soft-reset
while the TX delay retained it's previous state. A hard reset enabled
the RX delay while the TX delay was disabled.
Because of this inconsistency, wrongly specified PHY-modes were working
correctly while the hardware was in a different state.
Fix the PHY-modes of some affected devices (and clean up misplaced
properties along the way) to keep the devices working flawlessly with
kernels >= 5.1.

Header is located next to reset-button
There is also a Micro-B USB-port present but this only seems to be a
dummy as the circuit next to it is not present (at least in my unit).
It is also not mentioned in the devolo manual.
Installation
------------
Make sure you set a password for the root user as prompted on first
setup!
1. Upload OpenWRT sysupgrade image via SSH to the device.
Use /tmp as the destination folder on the device.
User is root, password the one set in the web interface.
2. Install OpenWRT with
> sysupgrade -n -F /tmp/<openwrt-image-name>
