Revert "Revert "ide: try to use PIO Mode 0 during probe if possible""

This reverts commit 24df31a.

The root cause of reported system hangs was (now fixed) sis5513 bug
and not "ide: try to use PIO Mode 0 during probe if possible" change
(commit 6029336) so the revert was
incorrect (it simply replaced one regression with the other one).
