pata_amd/pata_via: de-couple programming of PIO/MWDMA and UDMA timings
* Don't program UDMA timings when programming PIO or MWDMA modes.
This has also a nice side-effect of fixing regression added by commit
681c80b5d96076f447e8101ac4325c82d8dce508 ("libata: correct handling of
SRST reset sequences") (->set_piomode method for PIO0 is called before
->cable_detect method which checks UDMA timings to get the cable type).
* Bump driver version.
