Some of the other quirks changes seem to have left some users with the simplex
bits mis-set by the time the driver loads. Clear simplex mode before we probe
the controller therefore.

Since I saw some automated akpm mail about this... this patch is
obsolete. Needs ata_pci_bmdma_clear_simplex() at least.
Also, Tejun, you had some thoughts on this?
In current #upstream, we still call ata_pci_bmdma_clear_simplex() before
pcim_enable_device() in some cases, so the problem remains...
