Would it be even better if DSA had some driver-level prerequisites to
impose for ACPI support - like phylink support rather than adjust_link -
and we would simply branch off to a dsa_shared_port_link_register_acpi()
function, leaving the current dsa_shared_port_link_register_of() alone,
with all its workarounds and hacks? I don't believe that carrying all
that logic over to a common fwnode based API is the proper way forward.
