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.
