libata: convert the remaining SATA drivers to new init model
Convert ahci, sata_sil, sata_sil24, sata_svw, sata_qstor, sata_mv, sata_sx4, sata_vsc and sata_inic162x to new init model. Now that host and ap are available during intialization, functions are converted to take either host or ap instead of low level parameters which were inevitable for functions shared between init and other paths. This simplifies code quite a bit. * init_one()'s now follow more consistent init order * ahci_setup_port() and ahci_host_init() collapsed into ahci_init_one() for init order consistency * sata_vsc uses port_info instead of setting fields manually * in sata_svw, k2_board_info converted to port_info (info is now in port flags). port number is honored now. Tested on ICH7/8 AHCI, jmb360, sil3112, 3114, 3124 and 3132. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
