ide: sanitize ide*_pm_* enums
* Move ide*_pm_* enums from ide-io.c to <linux/ide.h>. * idedisk_pm_* -> ide_pm_* * ide_pm_state_* -> ide_pm_* * No need to set ide_pm_* enums to the fixed values. * Uppercase ide_pm_* enums. * Fix/update comments. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
