[SCSI] advansys: Move to scsi hotplug initialisation model
- Switch from scsi_register/scsi_unregister to scsi_host_alloc, scsi_add_host, scsi_scan_host and scsi_host_put. - Rename the scsi_host_template to advansys_template - Use module_init and module_exit instead of scsi_module.c - Remove protection against advansys_detect being called twice Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
