FS#13560: ATA: Don't check for 80 pin cables on SATA devices.

Browse source 
On PATA, we'd cap our transers at UDMA2 if the device reported that an
80 pin cable wasn't detected, but SATA devices do not perform this test.

So alter the check to only apply on PATA devices, so that SATA devices
can run at full UDMA speeds.
