Subject: [PATCH 7/7] ide-pmac: move ide_find_port() call to pmac_ide_setup_device()
Move ide_find_port() call to pmac_ide_setup_device().
While at it:
- fix return value (s/-ENODEV/-ENOENT/)
- add DRV_NAME define and use it to set name field of pmac_port_info
- use ide_find_port_slot() instead of ide_find_port()
- remove superfluous error message (ide_find_port_slot() takes care of it)
- drop IDE interface number from driver banner message (but include bus type)
