According to motorcomm,yt8xxx.yaml, the compatible string must be
only 'ethernet-phy-id4f51.e91b'.
Remove 'ethernet-phy-ieee802.3-c22' to fix the following dt-schema warning:
imx8mm-kontron-bl-osm-s.dtb: ethernet-phy@0: compatible: ['ethernet-phy-id4f51.e91b', 'ethernet-phy-ieee802.3-c22'] is too long
from schema $id: http://devicetree.org/schemas/net/motorcomm,yt8xxx.yaml#

The OSM spec defines dedicated functions for all pads of the SoM.
Therefore we can assume that carrier board designs stick to these
definitions and extend the SoM devicetree include with matching
default nodes and pinmux settings.
This way we can reduce the overhead and redundancy in the carrier
board devicetrees while still sticking to the policy of separating
board and module description.
Even if the carrier board design deviates slightly from the spec it
can define its own pinmux definitions and use them as necessary or
even disable unused nodes from the SoM devicetree.

The PUE bit is only effective if the PE bit is also set. To avoid
confusion, disable the PUE bit if it is not needed.

The current state of the devicetree for the i.MX8MM OSM-S and the BL
baseboard reflects deprecated prototype hardware. Update the board
description to match the latest hardware revision.
As the old hardware is not available anymore, was only produced in
very small quantities and was broken in some ways, we can safely
fixup the original devicetree.

OSM-S board
Some signals have external pullup resistors on the board and don't need
the internal ones to be enabled. Due to silicon errata ERR050080 let's
disable the internal pull resistors whererever possible and prevent
any unwanted behavior in case they wear out.

OSM-S board
These signals are actively driven by the SoC or by the onboard
transceiver. There's no need to enable the internal pull resistors
and due to silicon errata ERR050080 let's disable the internal ones
to prevent any unwanted behavior in case they wear out.

This adds support for the Kontron Electronics SL i.MX8MM OSM-S SoM
and the matching baseboard BL i.MX8MM OSM-S.
The SoM hardware complies to the Open Standard Module (OSM) 1.0
specification, size S (https://sget.org/standards/osm).
