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. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
