ide_platform: remove struct hwif_prop
* Remove 'if (hwif != hwif_prop.hwif)' check from plat_ide_remove() (pdev->dev.driver_data and hwif_prop.hwif are set at the same time in plat_ide_probe() and are identical). * Use hwif->index for ide_unregister() in plat_ide_remove(). * Use local variables instead of hwif_prop.plat_ide[_alt]_mapbase in plat_ide_probe() and remove no longer needed struct hwif_prop.
