Support U160 on 53c1010 chips.
Add support for PPR negotiations and DT transfers,
and the preservation and restoration of the
SCNTL4 register which controls Ultra3 transfers.
Redo sync lookup, since the same period factor
can mean two things depending on whether you are
using DT or ST. Keep a minimum allowed ST period
factor, and a minimum allowd DT period factor for
each adapter.
Currently NO support for QAS or IUS or AIP.
