libata: convert ata_pci_init_native_mode() users to new init model

Convert drivers which use ata_pci_init_native_mode() to new init
model.  ata_pci_init_native_host() is used instead.  sata_nv, sata_uli
and sata_sis are in this category.

Tested on nVidia Corporation CK804 Serial ATA Controller [10de:0054]
in both BMDMA and ADMA mode.
