hwdb: ieee1394-unit-function: add Tascam IF-FW/DM mkII

Jörg M. Sigle contriutes configuration ROM image for Tascam IF-FW/DM mkII,
which includes a quirk that the values of model fields in both root and
unit directory entries are different. In device attributes, it appears
that the value of model attribute in unit device is different from the one
in node device.

This commit adds hwdb entry for the model.
