Revert "Revert "ide: try to use PIO Mode 0 during probe if possible""
This reverts commit 24df31acaff8465d797f0006437b45ad0f2a5cb1.
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 6029336426a2b43e4bc6f4a84be8789a047d139e) so the revert was
incorrect (it simply replaced one regression with the other one).
