ide-pmac: store pmif instead of hwif in ->driver_data (take 2)
* Pass pmif instead of hwif to pmac_ide_do_{suspend,resume}().
* Store pmif instead of hwif in ->driver_data.
* Use dev_get_drvdata() instead of ->hwif_data to obtain pmif.
v2:
* Build fixes from Stephen Rothwell.
There should be no functional changes caused by this patch.
