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().
