Transfer responsibility to allocate/init hpriv from LLD/port_info to host allocation. All host allocation/prepare routines now take @hpriv_hz and initialize host->private_data accordingly. hpriv area is aligned to __alignof__(long long) and zeroed. As hpriv handling is moved to host allocation, pinfo->private_data is removed. The only user of pinfo->private_data was ata_pci_init_one() which is updated to take @hpriv argument directly. This change makes port_info carry one less host-wide info - which is good because mismatched scope causes confusion and bug (e.g. ata_piix private_data init bug).

A nice model to follow is netdev_priv() and the alloc_netdev() allocation code...
