mvebu: backport Turris Omnia DTS changes to 5.4 

Kernel 5.4 receives a reduced set, just to make the SFP cage work.
While we are at it, move the patches accepted upstream to the 0xx series.

Subject: ARM: dts: turris-omnia: add comphy handle to eth2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The eth2 controller on Turris Omnia is connected to SerDes. For SFP to
be able to switch between 1G and 2.5G modes the comphy link has to be
defined.

Describe switch interrupt for Turris Omnia so that the CPU does not have
to poll the switch. We also need to to set mpp45 pin to gpio function
for this.

Subject: ARM: dts: turris-omnia: add SFP node
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Turris Omnia has an SFP cage that, together with WAN PHY, is connected
to eth2 SerDes via a SerDes multiplexor. When a SFP module is present,
the multiplexor switches the SerDes signal from PHY to SFP.
Describe the SFP cage, but leave it disabled. Until phylink has support
for such configuration, we are leaving it to U-Boot to enable SFP and
disable WAN PHY at boot time depending on whether a SFP module is
present.

Subject: ARM: dts: turris-omnia: update ethernet-phy node and handle name
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Use property name `phy-handle` instead of the deprecated `phy` to
connect eth2 to the PHY.
Rename the node from "phy@1" to "ethernet-phy@1", since "phy@1" is
incorrect according to device-tree bindings documentation.
Also remove the "ethernet-phy-id0141.0DD1" compatible string, it is not
needed. Kernel can read the PHY identifier itself.
