[PATCH phy-next 0/5] Lynx 28G SerDes: 25GbE support

[Vladimir Oltean]

This is the remainder of "Lynx 28G improvements part 2", previously
submitted here:
https://lore.kernel.org/linux-phy/176850672122.1082429.444623229961712368.robh@kernel.org/

but split up into smaller portions (merged separately):
- https://lore.kernel.org/linux-phy/20260226182853.1103616-1-vladimir.oltean@nxp.com/
- https://lore.kernel.org/linux-phy/20260321011451.1557091-1-vladimir.oltean@nxp.com/

What remains is the highlight feature (patch 5/5): support for dynamic
protocol changes to/from 25GBase-R, required by SFP28 modules. These are
used with the NXP LX2160A and the (Ethernet) dpaa2-mac consumer.

Patches 1-4 handle the following situation: with current device trees,
the driver will think 25GBase-R will work on a lane, but it may work or
may not. This is because not all lanes support this protocol. So we
modify the SerDes compatible strings to identify them, and we use a
driver-internal database to figure out on which lanes does each SerDes
instance support this protocol.

On current device trees, 25GbE is not supported.

Detailed change log in patches. Summary:
- reworded commit messages
- change match condition from dt-bindings change 2/5
- patch 3/5 is new (reject probing on devices with no OF node)
