Lynx 28G improvements part 2

This contains a number of changes deferred from part 1 (patches 1-6):
https://lore.kernel.org/linux-phy/20251125114847.804961-1...

They are reworked in ways detailed in their individual change logs.

I have a special request to linux-phy maintainers: after merging, please
provide a stable branch/tag of this plus part 1, that can be pulled into
netdev. It is needed because phy_exit() calls from consumers would
compile but would cause a functionally broken link, so we need a linear
git history to avoid (temporary) regressions.

  phy: lynx-28g: add support for 25GBASER

Vladimir Oltean (7):
  phy: lynx-28g: skip CDR lock workaround for lanes disabled in the

  phy: lynx-28g: probe on per-SoC and per-instance compatible strings
