serial: serial_cs: oxsemi quirk breaks resume

Quirk is applied on all cards with given manfid (is it that correct?).
Unfortunately, that quirk breaks resume on zaurus with billionton
bluetooth card inserted: c950ctrl is 0 and outb() faults.

I believe it is simply not a multiport card.  (info->multi == 1).  ...
...  confirmed by printks.
