libata: stop overloading port_info->private_data
port_info->private_data is currently used for two purposes - to record private data about the port_info or to specify host->private_data to use when allocating ata_host. This overloading is confusing and counter-intuitive in that port_info->private_data becomes host->private_data instead of port->private_data. In addition, port_info and host don't correspond to each other 1-to-1. Currently, the first non-NULL port_info->private_data is used. This patch makes port_info->private_data just be what it is - private_data for the port_info where LLD can jot down extra info. libata no longer sets host->private_data to the first non-NULL port_info->private_data, @host_priv argument is added to ata_pci_init_one() instead. LLDs which use ata_pci_init_one() can use this argument to pass in pointer to host private data. LLDs which don't should use init-register model anyway and can initialize host->private_data directly. Adding @host_priv instead of using init-register model for LLDs which use ata_pci_init_one() is suggested by Alan Cox.
