Translating the Linux implementation specific configuration into
DT properties directly is usually not the best way.

Could we instead have a lookup table by compatible string to set the
flags? It seems that there are lots of different flags but only a
couple of different users of this IP block. Also, the fact that
you are now adding yet another quirk tells me that the set you
define today is unlikely to cover all the future requirements.
