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.
