ide: fix 40-wire cable detection for TSST SH-S202* ATAPI devices (v2)

Since 2.6.26 we support UDMA66 on ATAPI devices requiring IVB quirk:

  commit 8588a2b7
  ("ide: add SH-S202J to ivb_list[]")

We also later added support for more such devices in:

  commit e97564f3
  ("ide: More TSST drives with broken cable detection")

and in:

  commit 3ced5c49


  ("ide: add TSSTcorp CDDVDW SH-S202H to ivb_list[]")

It turns out that such devices lack cable detection altogether
(which in turn results in incorrect detection of 40-wire cables
by our current cable detection strategy) so always handle them
by trusting host-side cable detection only.

v2:
Model detection fixup from Martin.
