ide: add ->port_init_devs method to ide_hwif_t
* Add ->port_init_devs method to ide_hwif_t for a host specific
initialization of devices on a port. Call the new method from
ide_port_init_devices().
* Convert ht6560b, qd65xx and opti621 host drivers to use the new
->port_init_devs method.
There should be no functionality changes caused by this patch.
