pata_sis: Remove bogus cable match

Some systems report SIS 5513 as both vendor/id and subvendor/id
string. In that case we can't distinguish the system by the id
svid/sdid and in fact the entry here breaks some boxes. At some
point we need to find another way to detect the Targa Visionary 1000,
until then this trades a hang for some users with lower performance
for others.

Closes: #12092
