ide: use ide_find_port() in legacy VLB host drivers (take 2)

* Add IDE_HFLAG_QD_2ND_PORT host flag to indicate the need of skipping
  first ide_hwifs[] slot for the second port of QD65xx controller.

* Handle this new host flag in ide_find_port_slot().

* Convert legacy VLB host drivers to use ide_find_port().

While at it:

* Fix couple of printk()-s in qd65xx host driver to not use hwif->name.

v2:
* Fix qd65xx.
