libata: remove no longer needed pata_winbond driver

Winbond W83759A controller is fully supported by pata_legacy driver
so remove no longer needed pata_winbond driver.

Leave PATA_WINBOND_VLB config option for compatibility reasons
and teach pata_legacy to preserve the old behavior of pata_winbond
driver.
