    ide: drop 'initializing' argument from ide_register_hw()
    
    * Rename init_hwif_data() to ide_init_port_data() and export it.
    
    * For all users of ide_register_hw() with 'initializing' argument set
      hwif->present and hwif->hold are always zero so convert these host
      drivers to use ide_find_port()+ide_init_port_data()+ide_init_port_hw()
      instead (also no need for init_hwif_default() call since the setup
      done by it gets over-ridden by ide_init_port_hw() call).
    
    * Drop 'initializing' argument from ide_register_hw().
