libata: make ata_pci_init_one() not use ops->irq_handler and pi->sht
ata_pci_init_one() is the only function which uses ops->irq_handler and pi->sht. Other initialization functions take the same information as arguments. This causes confusion and duplicate unused entries in structures. Make ata_pci_init_one() take sht as an argument and use ata_interrupt implicitly. All current users use ata_interrupt and if different irq handler is necessary open coding ata_pci_init_one() using ata_prepare_sff_host() and ata_activate_sff_host can be done under ten lines including error handling and driver which requires custom interrupt handler is likely to require custom initialization anyway. As ata_pci_init_one() was the last user of ops->irq_handler, this patch also kills the field. Signed-off-by: Tejun Heo <htejun@gmail.com>
