libata-sff: Fix controllers with no ctl port
Currently, ata_sff_softreset is skipped for controllers with no ctl port.
But that also skips ata_sff_dev_classify required for device detection.
This means that libata is currently broken on controllers with no ctl port.

So don't skip ata_sff_softreset, just skip the reset part of ata_bus_softreset
if the ctl port is not available.
This makes IDE port on ES968 behave correctly:
