Running 'make dtbs_check' with schema in net/marvell,orion-mdio.yaml

Fix them by removing empty ethphy subnode from dove.dtsi and describe
PHY on the relevant board .dts files level.

I don't think your description is correct. What i think is causing the
problem is that the ethphy subnode in dove.dtsi does not have an @X.
By moving it into the .dts file, you can then give it the correct @1,
or @3, which makes the linter happy. The kernel itself does not care
about this, it is an example of the linter being much more strict than
the kernel.
If you agree with me, please update the description.

Hi Andrew,
Thanks for quick reply.

Yes, it is exactly the case. The problem is after adding dummy address
e.g. ethernet-phy@0 in dove.dtsi 'make dtbs_check' shows warnings
about missing required 'reg' property, that's why ethernet-phy is
moved to .dts files.

This patch exactly fixes this issue by setting proper
ethernet-phy@<reg value> in board files.
In such a case would you like me to update the commit message to
better describe the change or do you have other remarks to the diff?
Best regards,
Michał

I would like the description to actually describe the problem, that
the linter allows ethernet-phy@X but not ethernet-phy. You description
does not make any sense to me, it is not an empty node which is
causing the problem, but that node is expected to have an @X.
