pata_cmd64x: revert commit d62f5576
Commit d62f5576 (pata_cmd64x: fix handling of address setup timings)
incorrectly called ata_timing_compute() on UDMA mode on 0 @UT leading
to devide by zero fault. Revert it until better fix is available.
This is reported in bko#16607 by Milan Kocian who also root caused it.
