I have no idea how this would work with the standard interrupt-map property,
since the legacy interrupt host is now the same device as the pci host.
Maybe it's better to move the legacy
this register so that common code can be
re-used on old h/w.

v3.65 version of the designware h/w, requires application space

All of the Application register space handing code are organized into
