libata: fix drive side 80c cable check, take 3

The 80c wire bit is bit 13, not 14.  Bit 14 is always 1 if word93 is
implemented.  This increases the chance of incorrect wire detection
especially because host side cable detection is often unreliable and
we sometimes soley depend on drive side cable detection.  Fix the test
and add word93 validity check.
