ide: use ide_legacy_device_add() for qd65xx (take 2)

* Add 'unsigned long config' argument to ide_legacy_device_add()
  for setting hwif->config_data.

* Use ide_find_port_slot() instead of ide_find_port() in
  ide_legacy_device_add().

* Handle IDE_HFLAG_QD_2ND_PORT and IDE_HFLAG_SINGLE host flags in
  ide_legacy_device_add().

* Convert qd65xx host driver to use ide_legacy_device_add().

v2:
* Update ali14xx, dtc2278, ht6560b and umc8672 host drivers.

There should be no functional changes caused by this patch.
