This difference between ACPI and DT really needs to be described in the
commit description.

For example, why is it acceptable to have a PHY in fixed-link mode if
we're using ACPI, and not DT?

If we look at the phylink code, accepting a PHY when in fixed-link mode
is basically not supported... so why should ACPI allow this?
